Explosive Vario?
 

Last week I flew to-and-from Calgary to participate in the Race Willi.

My flight back to San Francisco was Thursday, the first day of the new 'liquid' restriction tightened security.

It was a bit of a hassle to stuff my bug spray and sunscreen in my check bags, but all considering, it was quick and easy to get through the airport.

It wasn't until today while reading a NYTimes article on liquid explosives, that I remembered the trouble I had a week a go flying to Calgary—and how much worse it would have been if it had happened after the new security regime.

I generally carry my electronics in my carry-on—laptop, vario, 2 GPS receivers, digital camera, MP3 speaker box, and 2M radio. I don't like the idea of them getting smashed around in the hold. And I don't like the thought of them getting lost.

This has sometimes led to small delays as screeners pull apart my carry-on and ask what everything is. But I've learned to carry photos of paragliders (on my phone, in my digital camera, in my laptop) and the conversation usually ends in the screener wishing me luck on my next comp.

Last week, my bag was picked apart and selected for the 'baby wipe' explosive residue test. That's the one where they brush a piece of cloth over your bag and put it in the chemical analyzer.

I've been selected for this a lot. It takes less than a minute, the screen flashes green, and I go on my way.

This time, the machine lit up with unhappy red blocks that said "explosives detected".

"Interesting," I thought, "a false positive. I hope this doesn't take too long."

The screener called over a supervisor and they both wrote something in a log book. The screener then reset the machine (took a few minutes), grabbed a new baby wipe and retested.

Red again. A few more entries in the log book, and the screener took everything out of the bag to examine more closely. But no one seemed very concerned.

"How often do you get these false positives?" I asked.
"Not often with this strong a reading." Not the response I wanted.

One more reset and test isolated the problem to my vario. At this point I'm trying to think of how the thing might have become contaminated with trace explosives. Had I been flying out of a construction site (maybe, there was work on top of Snowbird) or near ski-patrol avalanche control explosives (possibly at Jackson or Snowbird, but unlikely), maybe near fireworks??

And I started planning my arguments to get on the plane as I was anticipating a long slog with the security people.

But they just put everything back in my bag, wrote something in the log, and waved me on.

If a similar thing had happened Thursday, I don't think I would have been allowed to fly.

For those who are interested, TATP is what the machine thought it sensed on the vario.

Race Willi Day 5: Scratching down the Range

Today was not unlike yesterday, but which some breaks in the clouds we were more hopefully of a valid task.

The task committee, concerned about thunderstorms, set an early launch, an early land-by and individual start, so we could launch and head out on course immediately.

Abe Laguna bravely launched first—taking the risk of sinking out. We saw him glide around the first ridge fairly low, but we didn't see him heading to the LZ.

Bruno Berti, making a special appearance on the last day, launched next and I followed him out.

There was lift, but it was light. We couldn't see Abe—he was either well down range on course or dirted.

Bruno and I worked the very light lift together, chasing what sunny patches crossed the ridges.

I was able to hang on until a good pack launched including Will, Keith, Gavin, Greg, and Nicole. Bruno couldn't hang on and sunk out early.

The rest of us worked 50fpm up lift together. It was slow, but a lot of fun scratching as a pack. As Nicole put it, we felt confident in everyone else's skills so we could form tight patterns, scratch close, and help each other out.

At one point I surprised myself by hanging out _patiently_ in light lift while the rest of the crew pushed forward into no lift.

My patience put me a few hundred feet above the pack and I was able to continue on a bit after Keith led pretty much everyone out on a death glide. They weren't going to make goal, so they were just going for as much distance as the could.

Will held on, not ready to give up. I came in a little over his head and we worked some more light stuff together. Unfortunately, it was beyond my skill to hang on, and I had to bail on glide as well.

Looking back over my shoulder I thought Will had pulled it off, reaching the top of the ridge, but when he went on glide he sunk as well.

In the end I made it a few kilometers past the main pack, Will made it a few past me, and Keith with the amazing glide on his Boomerang 4 actually landed 200 meters past me.

But the story of the day was Bill Hughes. Bill managed to hang on longer than the rest of us—long enough for the clouds to part, the hill to heat up, and the air to start rising. He, Amir (who launched late) and Peter skyed out and reached goal.

Nice flying guys!

I ended up 8th I think, but aside from Bill, Amir and Peter, we all scored pretty much the same. In the end I held on to my 6th place overall standing.

Race Willi Day 4: Naming the Trees

Today was far less exciting than yesterday. Forecasts called for overdevelopment and thunderstorms in the evening so we went up the hill early.

Unfortunately high cloud kept the sun away and hopes for an early task were dashed as several non-competitor pilots launched and glided down to the LZ.

There was a bunch of waiting and much jaw-boning about whether to cancel the day or not. Greg Babush felt strongly that we should wait in the hopes of a clearing. I thought it was dumb, we should call the day and get in a free flight—probably a sledder to the LZ.

The launch window opened, but no one wanted to fly without some evidence that there was a chance of going up.

The debate continued until Greg and I came up with a good solution—we'd just huck and see what happened.

When we announced that we where going to break to stalemate and launch, several other top 10 pilots joined in. Either we'd all go, find some lift and have a race, or we'd all sink out together.

Abe Laguna, suited up and ready to go from the start, was the first of the pack to launch. I came right after him (good launch, zero incidents—at least 5 helpful people had check my straps for me :-).

To our surprise we found light but workable light right off of launch. Working together, and thermalling gently, we rose a few hundred feet above launch and the rest of the field quickly hucked.

Unfortunately, the thermal we'd found was pretty much all the lift there was, and when it petered out, Abe and I found ourselves scratching ridges, then hillsides, then trees looking for something, anything to get us up.

On the bright side, winds were exceptionally light so we could fly safely very close to trees and rock. I felt close enough to the trees to start giving them names, though my interest waned after about 20 minutes of that.

I was also low enough that I started paying close attention to my 'glide to goal'—I'd set my GPS to show me the glide-ratio I needed to make the LZ, there was no way any of us were going out on-course.

About this time scratch-master-Gavin Zahner, who really likes naming trees, pulled away from the hillside, threw a few wing-overs and headed to the LZ.

It was a perfect signal and within a minute, the rest of us were following.

I arrived high enough to chuck a quick 2 rotation SAT and some light wing-overs before landing.

No one made it out of the 'bomb-out' cylinder and on course, so the day was void. But we gave it a shot and got down in time to update our blogs!

Race Willi Day 3: Keeping my Sh*t Together!
 

Ok, so remember in my last blog where I wrote about keeping the mental focus? Today I put that lesson to the test.

Launch was even stronger than yesterday and good pilots were screwing up and getting popped, dragged, and smacked. Multiple times.

But other good pilots were handling it well, so I, confident in my high wind technique, put myself in line 3rd or so to launch.

Before inflating, I built a good wall and checked carefully for any knots or line snags. Seeing none I inflated, but my timing was off. Whoosh went a gust, and "wheee" went Jeff.

In retrospect, I should have gone hands up and flown the glider off launch backward, rotating in my harness once clear of the hill. Instead I reamed the brakes to bring the glider down, knowing I'd get dragged a bit, which I was.

I was a bit embarrassed, but I wasn't the first, nor the last, to flub that day, so I brushed it off (and my glasses, flight deck etc...), and went about straightening out my glider.

A couple helpful, but overzealous folks on launch helped me gather up the glider, I cleared up the lines and went back to launch.

The comp has a two-flub rule—blow two inflations and go to the back of the line—so I carefully laid my glider out in a nice rosetta and put some tension on the A's to inflate the middle section.

A few seconds pass while I wait for a good cycle to arrive and Nicole Mclearn walks up to my wing and starts fingering the top surface.

"Something wrong?" I ask.
"I think you have a tear," she tells me.
"How big?"
"A couple inches."

Crap. I bundle up off launch, unclip, and rummage around in my harness pockets for patch tape. Another pilot, Natalya, helps me do a quick patch.

At this point I'm annoyed and also impatient as I'm watching the day slip away from me. With folks being slow on launch, and having to wait my turn again each time I pull off launch, it's getting late. There are still only about 6 people in the air, but they are high and well established at the start cylinder.

I'm going to need at least 15 minutes, maybe more, to go join them and the race start time is rapidly approaching.

So when we finish up the patch, I hop right back to the front of the line (I've still only had 1 launch attempt), but the people on launch are waiting for good winds, and blowing their inflations. The wait is interminable.

Finally the person in front of me gets off the hill. I walk over, layout carefully. Take a deep breather and tell myself to pull it together, the people who tugged the glider were just trying to help, leave your frustration on the hill, make the inflation solid ('cause the end-of-the-line is a long way back), and go fly.

I inflate the glider perfectly, everything looks good, I turn, and as I start down the hill something feels very wrong. My harness is slipping up my shoulders. I forget to reattach my leg straps.

Immediately I have only one thought: I am not leaving the hill with my glider. It can go fly all it wants but I am staying on the ground. I also can't help but think about the recent fatal accident in Valle when a pilot launched without her straps.

These thoughts happen in split-second timeframe. I shoot my arms straight up over my head and let the harness slip up and away.

I may have been a foot off the ground, and the moment my feet touch down, the same moment I feel completely free of the harness, I slam the breaks, stalling the wing back onto the hill, but absolutely ready to drop the handles and let the wing fly away if braking caused the glider to surge upward.

This entire incident takes no more than a few seconds and when all is done I'm maybe 10ft down the hillside with my glider lying on launch. With the help of various launch observers, I gather my stuff and with no prompting, head for the back of the line.

I feel clearly that the day is lost. There is no way I'm catching the people who've already launched, but much more importantly I just made a very stupid mistake. My reactions were good and I came away unhurt but this was a very serious lapse—like nothing I've done before in my 10yrs of flying.

Clipping back into my gear I thought about the cardinal rules I had broken that got me into this situation:


  • If you unclip anything on your harness, unclip everything.

    I had unclipped my leg straps (the only straps on my harness—it has integrated leg/waist strap) but I had left my flight deck attached to both biners which meant I couldn't really see my straps.

  • Never launch in a rush, frustrated, or distracted.

    I wasn't thinking about my launch. I was thinking about racing, and how I was falling behind before I was even off the hill.

  • Always pre-flight every time you prepare to launch.

    I had, as always, performed my pre-flight check when I suited up and got in line. But I hadn't before my two inflations.

So now I had to decide what I was going to do. After yesterday I had told myself I would me mentally tough and not let myself get rattled as I had by the knot I launched with.

I carefully checked my gear again (straps, risers, speed system, reserve handle, reserve pins, helmet, radio), took a moment to chill, and got back in line.

The launch window was still open, but the race start was in just a few minutes and I was now behind at least 15 pilots waiting to launch.

The launch was still strong and the wind was a bit cross from the west. Most pilots were waiting for the southern of the two launch slots which gave more room to kite in the cross winds and less rotor. So I was able to hop immediately into the northern, unwanted launch.

A quick pre-flight assured me everything was good, I had an excellent inflation and was off the hill and back in the competition.

The flight itself was relaxing and a lot of fun. I was able to leave my frustrations on the hill and focus. With the first 6 pilots at least 1/2hr ahead of me, I didn't bother trying to catch them, but instead challenged myself to make goal and to stay ahead of the rest of the pack—essentially deciding that my race was for 7th place.

Nicole Mclearn, who had been having some trouble launching (just the typical trouble getting a good cycle and inflation, nothing as goofy as my troubles) launched right after me and we flew most of the course together. In fact here is a photo of Nicole after we hit the first turn-point.

Nicole and I marked thermals for each other the first bit of the course and had a gorgeous climb out of the first turn-point, tip-to-tip for 2000ft.

As the race progressed, I pulled a bit ahead of Nicole by taking a more direct route to the 2nd turn-point, and after a bit of cliff-scratching between turn-point 2 and 3, I glided into goal, full speed bar, at 100fpm up as the valley lifted off, arriving 4000ft agl—plenty of space to throw down some asym-spirals, a nice long SAT and a few rolly-polly wing-overs.

I was 7th, 10 minutes behind #6, and 30 minutes behind Abe Laguna, the day's winner.

All in all, a solid effort. I was able to get over my lapse, focus on the course, make some time up on the guys ahead of me, and fly a fun safe route. In the end I dropped only 1 place, from 5th overall to 6th.

And from now on when I talk to students about the importance of pre-flight prep, it won't be theoretical. At least not for me.

Race Willi, Day 2: Knot so good :-)

What makes competing so interesting to me is how much I learn every time I fly. The lessons can fun, frustrating, and even embarrassing, but they are almost always useful.

And sometimes it's the same lesson again and again, beating itself into my head.

Hoping to avoid learning anything new, I strategized a bit this morning—telling myself that I should fly conservatively; aim for making goal with the lead gaggle, but not taking risks. If the opportunity presented itself to race, I would, but in general, I entered the day in excellent position and didn't want to lose it.

Then, I got flustered. Here is what happened: launch was strong and people were a bit hesitant to huck. To get things going, Will Gadd launched. It was strong, but he handled it well and flew straight into excellent lift.

I think Keith McCollough launched next, and then I was up. It was a strong A's/C's kind of day, and not one to dally. Pop the glider, turn and go. Avoid strong brake (that would just result in being snapped into the air and pulled back), and run hard to keep in front of the accelerating glider.

I performed a decent high-wind launch, as described above, but didn't have time to fully inspect the glider on inflation. I knew there weren't any major issues, but as I flew away from launch and started turning in lift toward the right (it was a right-turn day) I discovered the worst compression knot I've ever had.

My brake line on the right was knotted to the C's and D's just below the highest divide, middle of the right wing. I flicked the lines a bit—tugging won't help a compression know—and briefly considered an ill-advised stall, and idea I quickly discarded given my height, the blustery wind and the low likelihood that it would work.

So I decided to live with it. Unfortunately, this meant:


  • Right-hand turns (the direction of the day) were sloppy and slow.

  • I couldn't pressurize the right tip very well.

  • The glider flew like a car out of alignment, pulling right on straight glide.

This (Len warning, bad words ahead) fucked my concentration and put me in a lousy frame of mind to fly gusty conditions.

I told myself to pull it together and fly the course. But I was less confident, and less aggressive, in strong and blustery lift (with my right tip's deflation tendency) so I left thermals early that I could have topped out, and I chose not to scratch the rock faces as close as I could have.

On glide, I was able to press 1/4 to 1/2 speed on the right side only and lean a bit to the left to hold a straight line.

This all worked reasonably well and 1/2hr or 45 minutes into the flight I had my focus back and realized that I was behind the leads (Keith and Will) but holding fast to 3rd place—wounded glider and all.

My first lesson was simply this: the mental game, though probably not as much a factor in Paragliding as say Chess, matters. No matter what happens, you have to find a way to stay calm and focused. I let the knot disconcert me and flew timidly as a result.

My second lesson, well, it's one I've written about before. Patience. Yeah, I know, I did it again.

The course was a double triangle (same three points twice, and then to goal) and one point of the triangle was out in the valley away from lift. Hitting it the first time involved getting high, gliding out (sinking the whole way), gliding back (sinking the whole way) and scratching back up the face to launch (another one of the points).

My second time around I could see that the valley was shading in, and it was getting late—probably around 8pm. I knew that I needed maximum altitude to pass through the valley turn, back to launch, and into goal in a single glide.

Fully aware, I hooked a booming thermal, riding it to around 8000ft, at which point I knew what I had to do was top out the lift but I saw chance to leave early and catch Will and Keith, so I left.

You can probably guess the result: I made it back from the valley turn-point lower than the previous pass. It was later in the day, and the lift I was expecting was gone.

Abe Laguna followed me into the sink fest (why Abe??) and we scratched for a while before bailing to the landing field having missed the final turn-point.

Ouch. That dropped me from 2nd to 5th, and even worse, let Greg Babush pass me in the standings.

Lesson summary:


  • Keep the mental focus, not matter glitches.

  • Patience, patience, patience. Or less succinctly, there is a time to race, and there is a time to lock in one's lead over Greg Babush!

Race Willi!
 

I returned to San Francisco last week tired out from my 8 weeks of travel and flying. I had some truly amazing flights, which I haven't blogged yet... I was planning to back-date some entries, but at this point I'll just put up a summary entry.

Being back in San Francisco was nice. I got to sleep in my own bed and recover from the cold I picked up in LA. But something was missing... Yup, the epic flights. So this week, at the urging of our friends up north, I came to Golden B.C. for the Race Willi.

Golden is the home of Mt. Seven—a 7000+ ft peak at the northern end of a seemingly endless range. Mt. Seven has two launches—a lower launch with about 4000ft vert and an upper hike up with about 5000ft vert.

Because the lower launch is a drive up, that's what we are using for the competition. Not really an issue as 4000ft is a _lot_ of space to hook a thermal.

Today was the first day and with winds strong from the north, the task committee picked a 60km downwind task.

The Race Willi runs concurrent with the Willi XC Challenge—a hang gliding and paragliding friendly meet with self-reported open-distance or out-and-back tasks. This means that all Race Willi participants can also hand in their flights for the XC Challenge which has real cash prizes.

So there is benefit to completing the course and continuing to fly. It adds a little spice to the comp. Rather than judging your glide to just barely make it into goal, it could be worth your while to tank up and keep going.

But for me, today wasn't one of those days.

The day turned out to be turbulent but not nearly as lifty as typical for this range. At the start of the course thermals were topping out around 8200ft—10 to 15,000ft is more typical. This meant that we had to make each canyon crossing low.

Local pilots had warned me to not attempt to hop from Mt. Seven to the next peak on the range with anything less than 10,000ft msl. I think we all left with around 7500ft.

This led to some exciting and bumpy shear rock cliff scratching—again and again on practically every crossing.
On our second gap-crossing, frustrated with light lift, I bailed extremely low for the far ridges and holy cow, they worked.

I hooked a nice 1200fpm thermal and rode it up to over 10,00ft.

From there it was a matter of staying as high as I could while racing to catch the few gliders ahead of me.

I passed two gliders and with about 20km left there was only one left—Will Gadd. I pushed as hard as I felt comfortable in the bouncy air, but Will played with me a bit, letting me catch up a bit, and then bailing out for the next thermal.

Wanting to race, I stopped trying to gain height and measured my glide, arriving a few hundred feet over the goal field—and 1 minute 5 seconds behind Will for 2nd place.
