A Milestone!

Les Fermatures? Inacceptable! / Collapses? Unacceptable!
Collapses.
They earn an inordinate amount of attention from novice pilots, attention that has a flavouring of fear.As previously discussed (see 'Fear Factor'), fear is a useful tool if harnessed correctly. It helps identify that which we do not yet understand.
Collapses, for the most part, are an angle of attack (AoA) issue. A low angle of attack can disrupt the airflow pressurizing the wing, causing some portion of the leading edge to fold. This fold, either span or chord wise, and loss of rigidity in the wing is the collapse. Collapses are not to be confused with stalls, the byproduct of too high an AoA.
Recovery from collapses may be automatic via design (as is expected of EN A and B wings) or may require pilot input (as is sometimes the case in EN C and D wings).
The identification, management, and recovery from collapses should only be learned under the guidance of a qualified instructor.
Collapses are important for the novice.
A collapse occurs because of an (in)action on the part of the pilot, allowing the wing to achieve an AoA that disrupts the airflow into it.Knowing that the collapse is a byproduct of the pilot, the collapse can become a learning mechanism. Every collapse is the result of a mistake (though not every mistake results in a collapse). Accepting this means we can:
- Begin to dissect the situation that set up the collapse.
- Identify the sensations in the wing and harness just before and during the collapse.
- Test the results of our actions as we attempt to mitigate and resolve (and ultimately try to prevent) the collapse.
A case study from personal experience:
Early February. West Launch, Mt.Borah, Manilla, Australia.
The record setting rains had passed the week earlier, allowing the ground to finally dry out. The promise of a proper summer flying day in Australia. Upper winds were light from the west, the cloud base high and the air active. Heat collecting on the vast plain below launch was continuously rolling its way up and triggering off various points of this relatively flat top hill. What was affectionately known as 'idiot lift' was clearly abundant.I had had a couple of great flights in the mild days preceding, being able to take advantage of being 15 kg under weight on my high end EN-B to hook the relatively weak thermals and climb out. One flight over the back had set a personal best in both distance and duration, so I was eager to get flying and push further.
Boating around to the WSW of launch, I find and hook a thermal. While in absolute terms the thermal was not particularly strong, my limited experience leaves me with the impression of being on an express elevator to low Earth orbit.
The elevator drifts back, over launch, to meet up with other elevators that had popped off along the flat top hill. The wing begins to move around in this mixing air. I decide this is getting a bit much, exit my climb and begin to push north.
Without warning the left side of the harness drops.
WHACK!
Any thought of pushing north is forgotten. I am now above and behind launch and have no desire of going back into that mixing pot to try for the bail out LZ. The campground LZ a few km's behind launch looks inviting. I turn towards it, failing to connect the dots that the thermal I am still in is connected to the cloud 3000m above said camp ground. Long story, short - I end up smashing my personal best distance wise, scratching out 20 km total from the altitude gained in that single thermal.
The earlier collapse? A distant memory.
Dissection.
The wing:
A high end EN-B that was acquired in late summer the year prior. This new higher performance wing would react to the air much quicker than it's EN-A predecessor.
15 kg under max weight for this wing, meaning the wing would be less loaded and more prone to collapse.
The site:
The western side of Mt. Borah is more or less a table top ridge. Thermals from the valley below work their way up this ridge and trigger from a variety of points along the front of launch. This thermic air then churns as it combines until it settles into a new aggregate core extending to cloud base.
The pilot:
Novice rated with approximately 70 flights. Thermalling experience extremely limited with most active flying skills coming from a pair of SIV courses. Active flying technique limited to weight shift responses. Flying with basic toggle grip.
Action.
- A wing with a lower upper weight range was acquired. The wing used during the trip was relegated to mild day use only.
- More attention was given to the employment of ballast.
- Basic toggle grip technique was replaced by use of a half wrap to better feel changes in wing pressure.
- Coaching was sought out to improve thermalling technique.
- Adjustment to flying style made to keep wing loaded in strong lift (open carve to leave lift rather than fly straight out).
- Better attention paid to changes in atmospheric conditions and the role of ground moisture.
Collapses should be unacceptable to the experienced.

Paragliding Economics 101: First Wing Purchase.
Standing in the landing field.
Utterly jacked.
Conveniently forgetting the butterflies that swarmed your stomach on launch not even twenty minutes before.
Enthusiastically you demand of the instructor, "MOAR!"
Instructor replies, "VISA!"
Financial caution is thrown to the wind as animal spirits take over, seeking to repeat the same rush of adrenaline and endorphin.
A quick word on lessons.
The lessons are pricey - but worth it. The quality and quantity of instruction will have a direct bearing on our safety (and enjoyment) moving forward. There is little excuse to be self taught in this day and age, especially when it could fast track one to the emergency room (or morgue).With lessons, I can only offer this advice - find the best lessons you can afford* and complete the lessons in as continuous a timeframe as possible (fly every day back to back vs once or twice a month). You should finish with the ability to consistently launch, land, and soar in novice appropriate conditions. As well, you should be able to judge what is a novice appropriate site and what novice appropriate conditions are. If you feel you cannot accomplish these things upon award of a license, discuss with your instructor what remedial lessons are needed to correct this before flying on your own.
More on the economics of lessons can be found under Paragliding Economics 102: Lessons
Wing for student training? Rent.
A wing suitable for someone with a few flights under their belt is typically not the same wing they will want to fly upon graduation. As beginners, none of us understand what our flying style will be when we graduate or what wing 'personality' we would feel most at ease with. The process of learning is not only about learning how to fly, but learning what sort of pilot we will be. Different ratings, makes and models of wings present a very wide swath of potential choices. A school that carries multiple brands presents a chance to try the various flavours of beginner oriented wings over your learning experience.A school that allows you to rent means you have less risk of deciding prematurely. Pragmatically, a rental wing means you are causing typical beginner wear and tear (and it is ALOT of wear and tear) on a schools wing rather than your own.
Graduated with license in hand? Buy used, unless...
When it comes time to make the first purchase post graduation, buy used.The school should carry a number of trade in wings that pilots grew out of as their flying progressed (I am on my fourth). If the school can provide an objective inspection of the wing (including a porosity test), then you will have some idea of the remaining lifespan and potential resale value when upgrade time arrives.
Keep in mind that wings depreciate rapidly in their first year post purchase and again in their third year post release to market. The first year is the transition from 'new' to 'used' and the third year is typically when a manufacturer will deprecate the model in favour of a new design. These two times present great opportunities for purchase of used product.
In terms of resale, lower rated wings will retain resale much better than higher rated. Likewise more popular brands will retain value over those that are obscure.
... you can continue to rent, if it is available.
If you can find a killer deal on a used wing as you approach graduation and it is still early in the season, go for it.If it is late in the season or the deals are simply not there, rent (if you can).
Why?
When I have sold used wings in the past, it appears a 20 to 25 % reduction of residual value per year was needed to get the wing to move. I see wings that try to sell for more sitting for months, with weekly BTT posts trying to drum up interest.
So taking the $6000 worst case new purchase price (see School B in Paragliding Economics 102: Lessons) , an assumed 20% annual depreciation, and a $50 / day rental rate (see School A) - let's have a look at the numbers:
Year | Equipment value @ start | Depreciation @ 20% | Rental days @ $50 / day |
1 | $6000 | $1200 | 24 |
2 | $4800 | $960 | 19 |
3 | $3840 | $768 | 15 |
If you are like myself and work a 9-5/M-F job, 24 flying days in a year (let alone my first year) would be absolutely amazing. That would be 1 day a weekend for 6 months (those that can do both days a weekend have a flying partner, are single, or quickly will be).
Happy hunting.
Oh and remember - *EVERYTHING* is negotiable. Paragliding is a want, the money you have is a need. You want the lessons and gear, the school/gear vendor needs your money. Keep that in mind when it comes time to discuss price.
* caveat - just because a school charges less (or more) does not mean the quality is lower (or higher). Different schools run on different business models - some sacrifice margin for volume, others may charge less for lessons and look to make up the money in gear sales. Ask questions, a lot of them - if the price is significantly higher or lower than the local average, find out why.

The season comes to a close.
Not one to sit idle, I've decided to occupy this free time with an activity more or less shelved a few years ago (actually, in the interest of flying).
Those exploits with continue on under a sister blog - The ShootinOrange.
Otherwise, see all y'all in the air come spring.

Triumphant return? Not so much.
Saturday evening:
Then a wing pops into view, and another, and another. All in all, five wings are visible. Not far from launch, but making forward progress against the wind.
Given that the grand Canadian tradition of chucking students off on DHV 2 wings fell out of favour a few years ago, odds are a few might even be EN B's.
There is hope for the day.
A few FB messages and truck loads later, a group congregates on Bridal launch with aspirations of an hour or two of air time. The majority are the 'old timers', comp-esque pilots of varying experience (Alex, Martina, bi-polar curve - 'Do I fly a HG or PG today?' Martin, and 'Boombox Bacon Bra' Patrick from the States), though a few intermediates (George, Lee) looking to play with the 'big kids' round the flying group out. In addition, Nicole is out to enjoy sun and conversation while kindly lending her good hand in helping folk lay out.
Still in 'European Flying' mode (conditions only get worse, so get set up quickly), the kit is laid out, hooked up and donned.
Alex launches, turns a pair of figure-eights just to the left and climbs out of sight up on the ridge. Aside from a single tip tuck, the air looks fine. Martin, George, and Lee follow, though require a bit more boating back and forth to capitalize on a climb. In amongst this is an abort on my part as I get used to the 90 degree cross that frequently presents itself at the eastern edge of the Bridal 'bubble'.
Attempt two and we are off.
The leash for the pod slipped loose, can't ... get ... in.
ARRRGGGG!
Fly away from hill.
Five minutes of fighting results in the footplate flipping in amongst the straps and speed system.
Increasingly creative use of metaphors and a realization that I have been futzing around pretty close to where the reserve handle is.
Switching hands and tracing along the left side of the speed bag, the plate is flipped back through and feet are in the pod.
In this time, I have sunk into the rotor from the ridge/mound just to the west of launch. Two hundred meters up and left with very few options to try to climb out when most of the surrounding air is being driven down at -2.5 to -3.0 m/s. Getting creative with landing zones at Bridal is ill advised on the best of days, so scratching along the base of the ridge with hope of finding some Franken-lift in amongst the rotor is quickly ended and I head to land.
Livid.
Crossing the Rubicon and gloriously entering Rome?
Not today.
But...
It is at this point that I realize some of the growth that did occur while training overseas. Through this whole ordeal no mental effort went into managing the wing in the midst of the churned up lee-side thermals. I simply flew it with little concern for what the air was or was not doing, reacting as needed, when needed.
Strangely enough, I am more at ease and feel more in control of this EN C wing than I ever felt with my previous EN A or B wings. Then again, maybe that is normal?
Kelly once pointed out that with a wind above X kph, a windward face of a mountain will begin to trump the sunward face. Perhaps a similar analogy can be used here: with recent flying experience exceeding Y hours of airtime, currency will begin to trump a wings rating.

Ozone Delta 2 SIV: Accelerated Symmetric, Accelerated Asymmetric, Small Wingovers.
Collapses experienced outside of SIV environment have thus far proved to be equally as boring.
The wing appears to resist turning, even in normal flight until it has built up some speed. This may explain the effort needed to start a carve in a thermal, or post collapse behaviour in level flight.
On the contrary, once the wing has settled into a bank angle, the effort needed to keep it there is relatively little.
Such a dichotomous behaviour has drawbacks, as the transition from a tight 360 to a nose down spiral tends to happen very quickly in surprising contrast to the time/effort needed to originate the turn. But this is a wing meant for XC pilots that intend to remain fairly current (100+ hours/year) - so this sort of behaviour should not catch the pilot unaware.
That all said, the only real 'quirk' the wing has is the tenacity of a cravat in resisting recovery.

Ozone Delta 2 SIV: Full Stall (plus cravat clearing)
The brake pressure at the stall point is extremely pronounced. Simply put, there is no excuse for a pilot 'accidentally' stalling this wing.
Camera is leg mount GoPro with wide-angle, so the pulls are a lot deeper than it appears at first glance.

Paragliding Safety: Homeward Bound
"I fly a 'B' wing because it's safe", are the words heralding an eventual tree ornament.
It takes two to have a mid-air collision, but only one to avoid it.
Final Exam - Part Two
The wing pitches back slightly and bites in.
Pause. The vario starts to beep.
The beeping continues. This one is large enough to turn in.
A carve is begun.
Opened and closed with each pass, the carve divides down the distance separating the core and myself.
The vario beeps grow in pitch and frequency.
Glance up.
The wisps of a cloud being born.
Salvation.
1300 meters.
Kelly and Olle are within an easy glide. I join up with them over the small ridge line east of Paderno. We spread out, trying to find an elusive climb that will enable us to continue to the second leg of the triangle.
Ten minutes later, the ridge line delivers, allowing Kelly and I to continue southward. Olle remains, trying to top up before joining us. It is during this part of the flight that I begin to take notice of the wings tendency to 'sniff'. One of the tips will pull back slightly and release, repeatedly. There is something in the air that is causing this reaction, though I have yet to identify how this relates to any nearby thermals. Likewise, I begin to work with the wing, rather than against - once the wing is in a carve, it will tend to pull towards stronger lift. Also, when the wing initially hits a core, it pulls back slightly, but quickly bites in. It is obvious it will take time to adjust to the style of flying the Delta 2 wants vs. my previous EN-B wings.
Gliding southward past Paderno, we pause over the same factory I landed beside the week previous. We are below 500 meters, the wind is picking up, and climbs are becoming disorganized. Every attempt to climb out is bound by yet another low inversion and becomes wasted trying to drive back into the wind.
I lose sight of Kelly while focusing intently on trying to work through the inversion. Patience (or lack there of) gets the better of me and I set down in the field. Packing up, I see Kelly low, yet making his way back to the hotel.
Post mortum of the flight reveals that this was one of the most challenging flights for Kelly's thermalling courses and would rank on par with a decent XC course route.
Oh and yes, Olle and I missed lunch...
Again.
Final Exam - Part One
A rare west wind.
Kelly has ambitions of a twenty-five kilometer FAI triangle.
Landing options abound within a single glide of the ridge until past Paderno. Our XC quartet are becoming accustomed with the rougher air over the ridge and have started demonstrating the ability to carve and coarsely map thermals. In essence, we are becoming semi-autonomous. Our trio is beginning to rely more on Kelly for route planning and marking climbs in more troublesome spots than feedback on technique (as opposed to where we were two weeks earlier).
That is not to say there is no feedback on technique, as there continues to be plenty of it. But each of us now knows what specifics we need to address on our own and just because the course is coming to a close does not mean the learning will as well. On this day, Kelly is planning to pull together the basics he has taught us and allow us to synergize the components into a proper XC flight under conditions more challenging than we have faced thus far.
On the hill, Jim and Tim are launched. Spacing them apart by 15 minutes gives Kelly time to guide each via radio. Based upon their rapidly improving performance, it is difficult to imagine their flight hours being so few and their background being exclusively coastal soaring.
With the clock closing in on noon, Kelly suggests to both of the newer pilots that they avoid the ridge as we approach the witching hour and directs them to continue practicing over the flats.
Magnus leads the quartet out, followed by Ollie, myself, then Kelly. Initially we were going to look for climbs over the mound to the left of launch, but the ridges to the right had lit up in the time since the departure of Tim/Jim for the flats. Now given several options, each of us could take a different climb and give our group the best chance of getting away - if one climb is lacking, a pilot can quickly leave it and join a better yielding climb found by a teammate. This is the paradox of paragliding, being highly individualized yet relying heavily on teamwork. This practice of pimping lead Olle and Magnus to share a single thermal while I begin to search more westward, towards a steep sided gulley.
Lift is readily available. Leaning in, carving, and mapping an ongoing thermal, it does not take long to lock in the core and drift back over LaCassette (the launch now infamous with our group due to a guide sheet description that included the words, 'Do not launch east. Danger of death'). At the top of LaCassette, a pair of sunbathers lie unfettered by such a dire prediction. Attention lies solely with the sun and the ballet of wings overhead and could not be bothered by Chicken Little-esque ramblings on a piece of paper.
Staying true to its word, the Witching Hour arrives and brings some bite to the air. A slow, yet continuous, exodus of pilots for the flats begins. By the time I decide I've had my fill, Olle and Kelly are already several kilometers downwind, passing north of Paderno. None too keen to apply speed bar under these conditions, I plod along at trim speed and stay just at the edge of the ridge's rough climbs.
I arrive just north of Paderno and face a crossroads, push out on the flats and risk sinking out OR try a climb up the 1500 meter rock faced ridge and receive another shellacking like I did the week before.
Flats it is.
The sink alarm starts to drone ... -2.5, -3.0, -3.5 meters a second. My flight is going to be all for naught if I can't find something soon.

Going Places - Part Three
Thursday, 11 July 2013
Going Places - Part Two
Pushing further and further out, both Kelly and I search for the first thermal that will allow us to climb out and begin the planned westward open distance run parallel to the ridge line.
In the midst of this initial hunt, I failed to realize that the distance between us was ever so gradually decreasing, until I was almost within 30 meters of Kelly. It is when he begins a right hand turn, in what I suspect is the beginnings of lift, that I notice we are too close and veer off aggressively to the right as well.
A chiding on the radio quickly follows. Flying in formation, hunting for lift is something I never did before this course, so my understanding of gaggle etiquette was somewhat lacking, to say the least. Mental note is made to follow up on proper positioning and distance under these circumstances.
My movement to avoid a conflict with Kelly drives me directly into the lift that he was moving towards. I lean in and progressively apply inside brake. As the wing begins to dive into the turn, a light amount of outside brake is applied to plane the wing out.
And so begins the thermal dance.
Working progressively into the core of the thermal, I climb up to join two other wings that had launched previously. Kelly is not far behind, climbing in a much more efficient and organized manner than I can manage at this point. Behind him is Olle, who has launched in the midst of the search by Kelly and I. Rounding out our XC quartet is Magnus.
Kelly quickly passes me in the climb while I am being hounded by a red Nova that can't seem to make neither heads nor tails of the thermal layout. On two occasions I manage to cut inside the Nova and climb five meters above, only to fall out on the other side. The fact that I am even attempting this is a very good sign, as it means Kelly's focus on efficiency in the climb are beginning to take root with my flying style.
I continue my climb towards a newly forming cloud when I hear mention from Kelly to Olle on the radio to look at continuing to the next ridge. I continue for another few turns, feeling the air go cold as I work through the inversion.
A few extra turns and I begin moving westward along the ridge. Something strikes me as odd that Kelly would continue in this direction as the conditions can only strengthen and become increasingly spicy on the ridge. Maybe he meant a different ridge, I wonder.
The radio chirps, "Mark, I am on you left, on your left."
A quick turn left, followed by
"Mark, I am on your right, on your right."
I can envision both Kelly and Olle right above me, having a good laugh at my expense. Then I spot them to the south, attempting to climb above a factory over Romano.
I begin my drive towards them...
Going Places - Part One
Tuesdays menu brings us another east wind day, so...
A Costalunga we go, we go...
A Costalunga we go.
Upon arrival it is quickly obvious that the aggregate thermic and meteo winds are not for the faint in heart nor the low in experience (for the folk back home, think mid-summer on the Mt.Woodside launch between 1:30 and 2:00 PM).
Kelly informs Tim and Jim that it is best that they sit this one out, the gusting conditions are very different from the laminar wind found at the coastal soaring sites that they are accustomed to.
A quick briefing from Kelly for Olle, Magnus, and I indicates Kelly will launch first and mark the first climb. We are expected to follow him out quickly, thermal up, and begin moving S/E - more or less with the wind, but also away from the ridge which is expected to bring rather sporty flying conditions as the day progresses.
As we finish setting up, two vans stop in the sliver of a parking lot above launch.
The Belgians.
Aside from the hotel patio at breakfast and dinner, we rarely run into this group. The only times I have seen them in the air have been in the early morning or just before sunset. I think it safe to assume that they are in the early stages of a Novice/EP/P-2 -esque course of instruction.
You can imagine my surprise when they showed up at this launch, at this time of day. Trebucheting beginners with the active flying skills of a brick off of Costalunga near midday. <insert Guinness 'Brilliant!'/> Paraglider manufactures have done quite a remarkable job technology wise in denying Darwin his due over the years and I start to wonder how quickly the first rung of the 'insurance' overdraft flow (passive safety) will be reached by this group.
Through all of this, Kelly has finished clipping in and is awaiting a lull in the gusts. Keeping my wing in check with a firm grip on the C risers, I alternate between watching him, the wind sock and the trees to my left (which are outside the launch 'bubble').
A lull.
Kelly launches, calmly and smoothly. There is little movement in his wing as he heads out, searching for the first thermal.
The lull continues.
Never look the proverbial gift horse in the mouth.
I pull up, keeping reign on the C's in anticipation of a renewed gust.
The lull surprisingly continues.
I turn, pausing ever so briefly to ensure the wing is settled overhead, take a pair of steps, and lift off.
Taking up a position approximately seventy meters to the right and behind Kelly, the search for the first climb of the day begins...

Paragliding Safety: Fear Factor

Paragliding Safety: Idiocy
Sunday, 7 July 2013
Feeling the air
It is Friday and week one of thermal/XC training is drawing to a close.
A proper send off flight is planned for Matt, Paul, Bev and Maurice -> meet in the parking lot at 0730 and head up to the high (1500m) launch for a smooth 20+ minute sled ride down to the hotel LZ to grab breakfast.
The conditions are perfect, actually beyond perfect. Thermic cycles are already making their presence known on launch by the time we arrive, an hour after leaving.
After the mandatory group photos ('everyone say fromaggio'), the crew kit up and launch in rapid sequence. The cycles are allowing later pilots to actually climb 20+ meters above launch, lazily circling in wide, docile lift.
I am next to last to launch, figuring the conditions and huge launch slope will allow an opportunity to try out a variation of the forward launch that Kelly had suggested previously to fellow student. I call it the 'refrigerator', as opposed to the 'boat tow' I had learned as a student.
Once off in the air, I don't waste any time playing with the others in the weak thermal to the right of launch. Instead, I pass by them and stay right along the edge of the ridge. Riding every little bubble coming up, I try to capitalize on the Delta 2's remarkable speed and glide ratio. I can see that a pair of wings are considering following me, but they quickly veer off upon seeing that others in the group are climbing closer to launch.
I am left to my solitude as I continue my run further and further west along the ridge.
Directly to the north of the hotel and near the crest of the ridge, I arrive at a plateau adorned by a single homestead and a pair of pastures.
I wonder.
I pause and began a slow circle, trying to sniff out lift. This proves trickier than it sounds, as I had left my variometer on the charger in room with expectations of a sled run.
I did not have long to wait.
The wing pitches back slightly and signifies that I have come across a thermal. Relying only on the wing movement, brake pressure, and a visual confirmation of my height, I remain in the air for an hour and a half in extremely light lift, only turning towards the LZ when there is just 15 minutes left to breakfast service.*
It is remarkable how attuned one can become with a wing when a basic sense (the beeping of a variometer) is taken away. The pitch and dive indicate more or less perpendicular interaction with lift/sink, while drops in brake pressure give a sense of lift boundaries crossed by a wingtip.
With this flight, I begin to understand what Kelly means when he states that the skills he is teaching us are akin to learning to employ a watch makers screwdriver, when most pilots can only employ a sledgehammer. Light conditions such as these require smoothness, finesse, and sensitivity if one wishes to remain aloft.
Sometimes the best lessons are the ad hoc ones for which a lesson plan was not prepared.
* - The high point of this early morning thermal dance was arrival of an impromptu partner, a 'local'. I had heard rumour that the local birds of prey frequently join in and remain with thermaling gliders, as our size and cast shadows tend to scare otherwise motionless rodents hiding in the fields below - effectively flushing out prey.

Paragliding Safety: Surrender
Flying Outside the Risers
Wednesday, it's Wednesday...I think.
The days have faded into a blur, where the only reference to a particular day of the week is which night the restaurant at the hotel is closed. Life is evolving into a paragliding equivalent of 'Groundhog Day' - up at 5, bank machine hunt at 5:15*, back by 6:45. Skype at 7, breakfast at 9, meet at 10, leave at 10:15, retrieve by 3, meet at 4, leave at 4:15, retrieve by 7, dinner by 8, sleep by 10. Repeat.
* - (Saturday note) after a week and countless kilometers of walking, I have finally managed to find a bank machine that actually exists, is within half an hours walk, and works with a Canadian debit card.
Wednesday, it's Wednesday...I think. Yes, it is Wednesday and we are on the lower launch (there are six launches in the area, but our group has been exclusively using only two, depending on winds and cloud base). The crew are getting into the swing of things, refining their carve and thermal mapping skills to the point they are beginning to climb out with little prompting on the radio (aside from the occasional, 'See that red wing to your left, it is climbing', hint to go capitalize on a new thermal sign).
I am last of the students to launch, again. I head for the house thermal to the left (the 'mound') to join Matt who has marked the climb and has set up a clockwise turn direction. I scoot in behind him, from the outside, as he climbs past me. I can envision the smile on his face as he sees the top of my wing for the first time this week - the 'old dog' is getting schooled.
The radio chirps with a prompt from the instructor to one of the newer pilots. The pilot is getting low and at risk of sinking out, a suggestion is made to go and join us.
I see Matt above me hit the inversion, likely noticing that two wings are climbing up to join him. He heads off southeast towards the flats.
I figure I have a little time to try and see if I can grab a core that could bust the inversion and open the opportunity to move higher up on the ridge to the east. A glance down changes all that.
The newer pilot has hooked a good climb, quite possibly the core I am looking for, but is turning counterclockwise.
I figure eight out and back in to join him in the same turn direction. My hopes for the core being strong enough are dashed, as it washes out. My thermaling skill is not yet at the point I could hook inside and up on another wing, in a decreasing radius turn - doubly so with a student that is clearly 'flying within the risers' - oblivious of the world outside their harness/brakes and prone to abrupt changes in direction.
I head off after Matt onto the flats, watching a bee swarm of students gaggle inside a thermal closer to the LZ. One shake of the head and I veer further eastward.
A few stern words are heard on the radio and it is obvious someone got a bit close.
Upon landing, I come across a discussion underway about awareness in the air that could be summed up with:
1. Avoid a collision with another wing at all costs.
2. Right of way is to be given, never taken.
3. Be predictable.
4. Ridge/thermal rules are guidelines, not laws. Do not expect anyone else to follow them.
5. Never show the top side of your wing to anyone at the same altitude as you in a thermal (don't cut them off).
The learning never ends.

The Witching Hour
The hours and flights are quickly racking up. I am discovering and beginning to work on holes in my thermaling technique, developing my thermal 'sniffing', and even getting comfortable playing in traffic.
Skill, confidence and comfort with the Delta 2 are all growing to the point that another stair step up in my learning staircase may occur before I leave (most folk have a learning curve, I have a learning stair case where there will be little perceivable improvement for a long period of time until, magically, a sudden jump occurs).
On the high launch again for the morning flight. Cumulus clouds are forming two hundred meters above, making for an excellent opportunity to put into practice Kelly's sage wisdom. Kelly wants the low airtimers to go first so that he can focus on instructing them via radio in calmer conditions.
An hour has passed since the first students were off - happily thermaling up to cloudbase and moving west along the ridge and out to the flats. Kelly and myself are the only ones left. I set up to launch and subconsciously clue in on the sudden disappearance of my thermal markers, the clouds. No big deal, I like blue thermal days anyways.
I pull the wing up and begin my run to launch...
and discover Bassano's 'Witching Hour' in...
3 steps...
2 steps...
1 step...
I am off, not even in the harness, and the wing goes apoplectic. Continuous fall back and surge coupled with repeated sharp drops in brake pressure. I manage to get my feet into the pod and focus intently on keeping the wing straight overhead.
It was immediately obvious that I had my work cut out for me - trying to thermal a huge rock face that has been baking in the sun for several hours bound by a strong inversion right at it's top.
I key the ptt for the radio, "Kelly, I hope everyone is off and away, it is absolute rock and roll out here now."
I let up the button to suddenly find my wing snap back and decide to time travel or dimensionally displace, all I know is what was over my head wasn't a wing anymore.
With a 'CRACK!' it reappears.
Guess it didn't find anything particularly interesting during its jaunt.
Key the ptt again, "This is Mark, did you see my blow out?"
"You had a blow out?"
"Yeah, I'm heading out to the flats."
Five minutes later, I gather Kelly is in the air when the call comes out on the radio,
"Guys, get away from the hill, I repeat, GET. AWAY. FROM. THE. HILL. It's the Witching Hour."
What had been perfect student conditions on the ridge an hour before had quickly gone advanced shortly after the novices in the group left for the more docile flats. Kelly's emphatic statement made it clear that conditions were no longer suitable for them to consider returning to the ridge.
Kelly is very firm in his belief that aside from leeside variants, inversions are a pilots worst invisible enemy in seemingly flyable conditions (gust fronts rank highly in his opinion of dangers, as well, but are relatively predictable based upon observation of clouds and terrain). I am pretty sure his years of flying in Bassano helped cement this belief, and this opinion appears to be shared amongst much of the European flying community. Case in point, I recall Jocky advising one of the Swedes to be very careful of the inversions in Bassano.
Having taken about half an hour to settle into the conditions for the day and get back in sync with the wing, I begin trying to repeatedly work through four distinct layers of inversion, at 650, 800, 1000, and 1300 meters. An hour passes and my attempts come to an end as I land south of a factory a few towns to the east.
Turbulence tolerance *= 10;
Retrieval deja vu -> missed lunch, heading back up in the hill in half an hour.
By the time we were at the lower launch, conditions were clearly baked and a sled ride was all that would be had. Facing such an anti-climactic end to the day, I chose to ride down. The thermaling snob refuses to submit to a five minute sled ride after staring into the jaws of the dreaded 'Witching Hour' ;)
Dinner. Sleep. Repeat.

Lost and Found
Gear, clothing, suitcases torn apart and strewn all over the hotel room.
A robbery?
No.
A missing radio.
After having flipped the room twice since pulling everything out to recharge, it becomes quickly apparent that my radio is no longer in my possession. A dreadful certainty fills me on where it is, the hayed field in the middle of nowhere that I landed in the evening before.
A plan forms. It is extremely unlikely anyone would walk the maze of dirt roads I took to get out since I landed and it is equally unlikely that a farmer will work the field right at sunrise the next morning.
445 AM.
The only things up and about are the rosters, the local constabulary, and myself. Winding my way along dirt roads, through fields, and over rivers I come upon my landing field to see sitting in the wet hay one black Yaesu VX-8DR.
Success.
Back at the hotel by 7AM, I find myself tired but content. Replacing a radio in an area with so few amenities/shops would be next to impossible.
A few hours pass and our group meets Kelly on the hotel restaurant patio for an overview on thermal carving and mapping, along with the meteo conditions. Today is looking like a 'fizzy' day -> low cloud base means the notorious Bassano inversion has taken a day off and the thermals can be expected to be frequent, short lived, and soft edged.
We set off for the high launch to the east. Setting up our kit at 1,500 meters, we are all but touching cloud base without leaving the ground. Kelly makes it clear not to enter the clouds and that if we are getting sucked in, push out away from the hill where the clouds have yet to invade the flatlands.
The plan from Kelly was for him and I to launch last, herd up what cats were still in the air, and head off on an XC.
No flight plan survives contact with the hill.
A comms issue with Kellys radio left me out of contact with him for 10 minutes and I figured he wasn't going to fly after all.
New plan, free fly a 15 km triangle along the ridge, into the flats and back. An increasing northwest head wind up top frustrated my final leg, and down I went.
An out landing, a missed lunch, and a chastising for wandering off.
Half an hour after getting back to the hotel, I pile my gear into the van and off we go again. Not one to push the 'bad pilot' button too many times, the instructions are clear - stay up one hour, land at the hotel garden.
One hour after launching, I am alone in the air and make my way out to the flats. One of the Brits, Matt, very kindly radios up to ask which beer would I prefer on landing. Incentive to head down, if there ever was one.
Snap off a 90 degree turn above tree tops, surf in the Delta 2 hot, I land, turn and set it down in front of a crowded hotel restaurant patio. I do love this wing.
No applause.
Tough crowd.
Must be a panel of Russian judges today.
