Gravity, Wind and Dirt
June 8, 2002
I wrote the following after crashing (not tandem, but with another friend and pilot) a couple of days ago, writing helped clear my head up about the whole experience. We're basically OK, but it was a near thing. Here's the story, feel free to pass it around to anyone who might be interested.
A couple of days ago I had my first-ever paraglider crash. In the last eight years I’ve flown several thousand hours all over the world, generally in strong thermal conditions. I’ve set many distance records, competed occasionally and generally had a great time flying. I have always said that I would crash one day, it’s just statistical; you can do your best to avoid being a number on the crash side of the statistics chart, but sooner or later it’s inevitable, nobody is perfect all the time. My number finally came up three days ago.
Cochrane, Alberta.
The day looked perfect for XC flying. Cycles on launch ranged from 5 to 30kmh, a fairly normal setting for a south-west-facing thermal site at 2:30 in the afternoon. I arrived at Cochrane just as Tihi and Chris Muller were pulling out their gliders; both are good pilots, and Tihi is known as a fairly conservative pilot. I watched the cycles for a few minutes and thought conditions seemed reasonable, a judgment supported by Chris and Tihi who had been watching them for a while (they live at the hill). We talked on launch about how good it looked--Tihi and I were excited to go cross-country, conditions looked epic. There were good clouds drifting perfectly overheard, and my main goal was to get into the air and thermal up to them. I was fairly sure that we were about to have one fantastic afternoon of flying. We all laid out, clipped in and got ready to flap.
Chris launched first in a nice cycle that was blowing in at perhaps
10-15kmh. I watched him for a minute and saw that the air looked good. I
then saw him starting to climb in a nice thermal in front of launch, so
I pulled up, turned and started walking to the edge of the hill in a
smooth, 10kmh breeze. I was fairly far back from the rounded edge, maybe 20
feet, and just starting to get into the air when I saw the sock on launch go
from blowing gently straight in to directly across the hill and stretched
out like it was starched. Chris later estimated the wind speed at 35kmh. Not
good. I heard the wind roar, not a good sign, then was catapulted
straight up and onto my back. I knew from hitting a lot of dust devils over
the years that I had just hit another one; this time I was very low
(although I had just gained about 30 feet). Shit, this wasn’t good, and my
movement was only accelerating.
I could feel that I was moving quite quickly across launch to my
left, and that my feet were somewhat higher and to the right of my head. The
glider was lost; normally I can tell exactly what my glider is doing and
work with it, but there just wasn’t much to be done here. I spotted the
ground and saw that between me and it was Tihi’s glider--even though he
had been 30 feet to my left only a second before. Years of gymnastics and
diving kicked in and I was able to twist in the air and get my back
protection toward the ground and my head at least level. I remember thinking
clearly that this was going to hurt--a lot. I kept my neck turned to the
side to watch the ground and stay oriented as I fell, and noticed that Tihi
was just leaving the ground in the same dust devil that had grabbed me. Then
I went through his lines and hit hard on my back and side. I rolled with it
to dissipate the energy, but I’d hit pretty much straight on. I heard all
the vertebrae in my neck click just like they had years earlier when I’d
caught my heel side edge while going fast snowboarding; whiplash.
The impact partially knocked the wind out of me and totally
disoriented me. Once I came back mentally I could see Tihi downwind of me on
the ground (how did he get there?), which we were both getting dragged
across fairly fast. I did my best to disable my glider, but I was pretty
disoriented. Both gliders were spun up together but still catching a lot of
air. After about 50 feet we stopped. I lay there for a few seconds, then
moved all the major body parts and listened for the roar of pain I was sure
to feel. You don’t crash from 20+ feet at a high rate of speed without
breaking something. My neck was painful but felt exactly like it had after
my snowboarding crash, and I could feel I was generally bruised, but
amazingly the parts all felt more or less OK.
Terry, a hang glider pilot, ran up and asked what to do. I told him to lie on the wings to prevent us dragging more, which he did. Vincene, Chris’s mom, witnessed the whole thing from her living room window and also ran out and lay on the wings. Chris top-landed immediately beside us (conditions were now mellow again), and we started the business of figuring out what was wrong. I gingerly and slowly unclipped from my harness, but Tihi wasn’t moving much. I checked that he was breathing and responsive, then started the search for spinal or other injuries. He complained of mild pain in his neck and kept asking, “What happened?” I explained that we had crashed, and he asked if were flying. I said not really, then he asked what happened again. It was clear he had suffered a concussion. We put a collar on him, checked him very thoroughly for other injuries, then loaded ourselves into Vincene’s truck and headed to the hospital immediately. I kept mild traction on Tihi’s neck and stabilized it against the head rest. Mainly I answered Tihi’s questions on where we were and what had happened; fortunately the time interval that he didn’t remember was getting shorter and shorter, so things didn’t seem to be degenerating.
At the hospital the paramedics ran a quick check on my neck and
declared me to be whiplashed, which a doctor on his way home confirmed and
said they didn’t even do X rays unless I had direct spinal pain. The
medics were more concerned about Tihi, and ended up admitting him for
farther examination. Turns out he had a fracture of a small bone in his
wrist, a sore neck and a solid concusion, but was otherwise fine.
He had more injuries than I did, probably because I could see what was going
on and had prepared to crash while he had it happen much more suddenly.
As I write this I feel very, very lucky. Chris said, “That was one
of the most radical things I’ve ever seen on launch. I remember thinking
that you were very fit, but that you would probably be injured.” My neck
is sore, but everything works. This was my first "real"
paraglider crash (I had a rope break very low on a tandem tow once and a few
other incidents), but I’ve thought about crashing a lot and tried to
visualize getting oriented in the air and landing either on my back
protection or in such a way that I could roll and turn the vertical movement
into horizontal. I’ve always figured that I would crash either from a
mid-air in a gaggle or if I lost control of my glider below the altitude
where a reserve toss would do anything. Sure enough, that’s when it
happened. I fly with an extra-large reserve for the mid-air entanglement and
try to leave enough terrain clearance to either recover the glider or toss,
but you can’t always do that. I’ve been flying a lot in the last two
weeks, at least 30 hours of thermal air time, so I felt confident and clued
into the air but I keep asking myself what I did right, wrong, orcould
have done differently.
What I did right has more to do with luck, equipment and general
fitness than any particular skill. I was hearing a High Adventure XC
harness, which has excellent back and side protection. Due to gymnastics and
a lot of crashes on snowboards, skis and mountain biking I was able to get
the padding toward the ground and my arms tucked in to roll with the impact.
If I had of stuck a hand out I probably would have broken it. I was wearing
a good full-face helmet; I condensed the foam in the back of the helmet and
somehow broke the chin guard either while hitting the ground or being
dragged--either way my face would likely be more sore without the chin
guard. I had two helmets in my bag at launch, I choose to wear the full-face
because I knew I would be low to start, Cochrane is a small site and
requires scratching to get going. My harness has deep abrasions and impact
marks on it, but the six inches of back protection and side plates really
helped absorb a major impact. My glider, a Proton GT, is fine. I don’t
think it would have mattered what glider I was on, it was simply too much
too low for any wing to deal with. Tihi’s glider definitely slowed my
impact some, and Chris felt my falling through Tihi's wing kept Tihi
from getting yanked high into the air also. Dumb luck there.
What did I do wrong? Perhaps launching back from the edge of the hill
prevented me from seeing the dust devil’s approach; there was grass in the
air after it took Tihi and me out according to Chris and Vincene, so perhaps
if I had been on the edge of the hill I could have seen it or the violent
change in wind speed and direction coming in the short grass/bushes below
launch. I was flying in very strong mid-day conditions, but this is pretty
much normal for me, Chris and Tihi. There were some interesting
meteorological conditions in the area, but they were adding up to some great
flying potential, not out-of-hand conditions. After we crashed Tihi did
mention that he saw a large dust devil near launch earlier. But it
wouldn’t have made any difference if he had mentioned it before launching,
I would just have taken it as a good sign that the day was really on—dust
devils are the bottom of thermals. We all fly with dust devils mid-day at
any good thermal site, they are to be respected and feared but don’t shut
the day down in general. I’ve flown into small ones on the flats at low
altitudes, they are violent but manageable if you know what to expect and
have some altitude to deal with it.
What could I do differently? There might, might, have been enough time to collapse my glider when I saw the windsock change, but I don’t think I could have reduced the surface area of my glider fast enough to keep from getting sling-shotted. If I see the sock change that violently again I’m going to deflate my glider immediately and hope I can reduce its area fast enough; I have been hit by small dusties on launch before, but I’ve been able to run and just lie on the middle of my glider while it was blown around. I normally like to launch at the beginning of a lull on strong days, it gives me enough time to get some terrain clearance before hitting a strong cycle. I think that if I had of had even 100 feet and a fully loaded glider I could have sorted this out; my glider wasn’t yet fully loaded and I hadn’t yet developed a feel for what the air was doing. Chris had mentioned that the cycles were very strong and switchy, perhaps I rushed into the air to join Chris rather than picking my own cycle? I’ll definitely pay more attention to the cycles before launching. I have good confidence in my flying ability and the solidity of the Proton GT, but there are obviously some situations where you just need altitude to deal (either in a paraglider or hang glider). I also don't think I was mentally all "there" after crashing; it turns out that we made the right call about my and Tihi's injuries, but would it have been bette to call an ambulance? We did reach the hospital quite quickly, but if we had mis-diagnosed either my or Tihi's injuries then perhaps an ambulance would have been a good call? We could have back-boarded either/both of us; we all have good first-aid training and did the "right" thing luckily, but we're not paramedics. It's something to think about; I certainly have no negative comments on our actions, it's just something to think about and discuss for the future.
I
will continue to fly mid-day, but I will launch where I can see more of the
terrain in front of launch to judge what’s happening with the cycles.
Cochrane is a very small (less than 500 vertical?) site, I think I took it a
bit casually (it’s just not as impressive as hucking off of Walt’s or
Aspen or…), but mid-day conditions are mid-day conditions and need to be
respected.
Tihi
and I both feel we were incredibly lucky. I looked DOWN on the top surface
of his glider as I “flew” through the air, which means I was at least 20
feet in the air. I look at a two-story building and think about running off
and landing on my back, it’s a frightening image. Tihi’s concussion has
cleared up, and his wrist will heal in four to six weeks. Given what could
be wrong I feel incredibly lucky to be sitting here typing this and talking
about it with Tihi on the phone instead of in adjoining hospital beds!
Thanks to Terry Thorcan, Vincene and Chris Muller for their
effective and competent assistance; we are lucky as a community of pilots to
have them. Thanks also to Superfly for everything, including the good
helmet and High Adventure harness, they worked. Terry ended up flying 110K
after watching Tihi and I crash, so it was a good day! Rather than feeling
unhappy to have missed it I just feel lucky.
Safe flights!
