I don't know when I got the bug
to take up hang gliding, but an introductory lesson was supposed to have
been my birthday present some six months earlier. After several failed
attempts to line up lessons, my life partner Dani found a place in Houston.
She finally made arrangements for a couple days of lessons through them
on an upcoming weekend.
The class started off in a classroom at
10am Saturday. We ended up having an even dozen people (counting
Dani and me). My friend Valerie (who lives in Houston when she isn't
away in grad school or on an internship) met us there and brought her friend
John with her as well. John had been looking to take lessons coincidental
with our interest. When Val mentioned her plans for the weekend,
he wanted to join in as well.
The instructors were an interesting pair.
Fred was a retired engineer from NASA. He was about 70 and did most
of the talking. The other instructor, Bruce, was perhaps twenty years
young and was a lawyer. He only interjected bits every now and again
or spoke up when Fred defaulted to him for supplementary information.
Fred covered most of the theory behind how gliders work. He was heavily
into the math with a lot of physics terms thrown in like vector summation
and moment (a version of inertia relevant in systems involving rotation).
I think John (who is a physics major) and I (a high school physics teacher)
were the only ones who not only followed what he was talking about, but
we actually were interested. Eyes glazed over among the rest of the
class at the first appearance of the math, but Fred made the material reasonably
accessible by giving examples for each of the terms in the equation.
Specifically, Lift = 1/2 p v2 cl s. In plain English what
that means is that fast moving wind is most important to getting off the
ground (and staying there), but the angle the wings attack the wind and
the surface area of the glider (or plane, etc.) are critical as well for
reasons that ought to be obvious to anyone who has tried to keep an umbrella
over their head in a gusty thunderstorm.
The "lecture" wasn't really very organized,
but it was certainly entertaining. There were lots of anecdotes about
what happened to flyers when things went wrong. For example, pilots
not taking things into consideration all-important details such as attaching
their harness into the glider before launching or flying too close to the
low pressures of storm clouds and finding themselves getting sucked in.
The stories were always interesting, even if the presentation wasn't the
most manicured.
Around noon we broke for lunch and headed
down to a park a few miles away to practice running and launching... but
not actually flying yet. We learned how to assemble gliders by watching
and assisting the instructors as they put them together. They brought
out a pair of them, so we split into two groups by weight class and practiced
trying to get off the ground. This was all on a flat, level surface.
Short of an aeronautical miracle, there was no chance of us really taking
to the air just yet.
What you don't realize when you watch expert
flyers take off is that it takes a while to learn how to hold a fifty plus
pound glider and keep it steady while you're running. You need to
keep it straight on, not angled downward, upward, to the left, or to the
right, and the slightest deviation means the wind will magnify your error
into an impossible angle and bring the attempt to a swift conclusion.
Within the first few runs, the class had managed to end up turning every
possible combination of the wrong direction, and that's just getting started.
`
Once you get the glider up to an air-worthy
speed, you have to switch hand positions while still running. Your
hands are pointed downward as though holding a large golf club angled outward
in each hand, then you rotate them (while still in forward motion) so that
they're now holding the glider the way you would an umbrella handle.
Basically, you're running with a big chunk of mylar and metal that you
almost have to let go of completely to get in a position to push outward
so that the glider tilts up and catches the wind. You're doing a
lot of things at the same time that more or less have to be unconscious,
only it's all brand new, so you haven't learned them yet. Naturally,
you have to think about everything at once when it's happening entirely
too fast for you to think about. This is why the first lessons don't
involve even an incline, never mind running off a cliff.
There wasn't a lot of wind on this day
though, so we only just barely got off the ground most attempts, and that
was only if the run didn't end in a fall. I never fell, but several
other students did, repeatedly, in some cases. We continued cycling
through practicing our runs (and falls) until around 4pm, before we broke
for the day.
We were all exhausted and had the beginnings
of a real sunburn. When Val, John, Dani, and I all went out to dinner
that night, we were various shades of pink leaning toward the red end of
the spectrum. The plan was to see a late movie, but I reluctantly
played the party pooper and said I was too tired to stay awake through
one. The rest admitted they were as well. We were all in our
mid twenties to early thirties, and half a day of pushing a glider around
already had us worn out. We all headed off to bed relatively early.
Good thing, too, as the next day we went
out to a different spot (this time with a hill!) to get started trying
to fly a bit for real. Seeing as how Houston is basically flat, Fred
and Bruce brought us out to a levee where we could get a running start.
Aside from the fact that a raised incline provides flyers with some altitude,
there is also the benefit of what is called ridge lift. This is what
you get when wind is directed upward by the angle of the incline which,
in this case, was the levee.
There wasn't a lot of wind on this particular
day, but a little bit came and went while we were out there. On one
of his runs, John took off and was really flying (not just gliding a foot
or so off the ground like we had been up to that point). The wind
happened to come in at just the right moment, and he lifted smoothly up
about 10 or 15 feet in the air. Up to this point, no one in the class
had managed to get more than a couple feet off the ground. John was
as surprised as any of us. There was a mix of emotions on his face
as he yelled down to the rest of us, "What now?!" There was water
in front of him from the bayou the levee guarded, so he couldn't keep going
indefinitely, but he didn't want to come down on those of us who were crowded
at the bottom of the slope waiting for our turn.
There are two things you can control when
you're in the air: pitch (up/down) and yaw (left/right), and almost anyone
who willed themselves even a few inches off the ground (myself included)
seemed only to be able to do one or the other at a time. There were
a couple runs where I either started off in a turn or ended up in one,
and I never recovered. Thankfully all my landings were really good.
Whereas many students came down horizontally like they were sliding into
third base, I always landed on my feet, albeit somewhat awkwardly at times.
A lot of people just scraped along on their side or belly and knees.
One lady who took the lesson with her college-age daughter kept going down
on her hip like that over and over again. I have no idea what she
was doing wrong, but she managed to do it every time.
My best run was also my last of the day.
Every turn I had with the glider was better than the one before it.
I was integrating the information, and it was finally starting to become
natural. It was suddenly very windy as I got ready to start my run,
so I knew to hold off. As strong as the gusts were coming at me,
I probably could have lifted off without even running much. However,
I might simply have started flying backwards if the wind blew just a tiny
bit harder, and that wouldn't have been good. After all, given that
this was an introductory lesson, I still really had no idea what I was
doing.
I waited for a bit, then the wind calmed.
I started running, and somehow everything went perfectly. Whereas
many of my previous, windless runs didn't result in any real air even by
the time I reached the bottom of the hill and had maxxed out my speed,
this time I managed to take off about halfway down the incline. I
started going up and turning to the right. I was about ten feet or
more up (who can accurately gauge things in the moment?) and I was heading
for the crowd at the bottom of the hill same as John had earlier.
The problem here was that class was sitting on a large log of driftwood
deposited sometime earlier when the water was higher, so I couldn't just
expect the students to move and give me a clearing. Even if they
ran out of the way, I still might have run the upturned branch at the end
of the log right through the glider's canopy when I came down.
I managed to stay aloft heading toward
the log and crowd, but I had to decide whether I should try to go over
them or to take the glider down prematurely. I figured I had better
land since I couldn't tell how quickly I was descending as it was.
I jerked the glider down sharply and made a pretty good landing on my feet
considering how abrupt it was. John's most impressive flight earlier
beat mine in terms of time in the air and distance covered, but mine was
at least the second-best of the day.
My partner Dani didn't have nearly as much
luck in her attempts though. She had a lot of trouble taking off,
and I don't know that she really ever got herself adequately in the air
to say she was flying. She just couldn't run fast enough. Since
there was so little wind to work with, it was up to all of us to get up
to a critical velocity that she never achieved. Actually, the adjacent
portion of the levee that the lower weight class was using was about ten
degrees steeper, so the students on that one were able to get moving faster.
We switched over to that section later in the afternoon, but as fate would
have it, not for very long.
Toward the end of the day, Jose, a short,
stocky man in his early 50s tried the steep hill, but he was only airborne
for a second before he stalled and came down fast. On almost every
attempt throughout the day Jose tended to jump as soon as he got any lift
at all instead of trying to get more speed. Contrary to your instincts,
jumping does not allow you to fly. The only thing it accomplishes
is to prematurely put you in the air before you have been lifted there
via the glider. And if you're in the air, you can't propel yourself
forward with your feet. If you aren't gaining speed, then there's
nothing to keep you in the air. Guess what happens next?
Coupled with his predilection for jumping,
Jose was also one of the students who never landed on his feet, so on this
(his final) landing, the glider hit the ground on the left landing wheel
with him still hanging on. As a result, there was about 200+ lbs.
of glider and pilot on that corner of the frame. The two bars adjacent
to the point of impact buckled under the weight. Jose was fine since
the force of the impact was absorbed by the now-destroyed tubing, but this
was especially sad for me since I was next in line to go after him, and
I hadn't tried the steeper hill yet. This part of the levee also
had a several hundred more feet of dry land extending in front of it before
the water began, and I had every intention of covering that entire distance
of that on my next flight.
Unfortunately, the glider Jose crashed
was the one for the heavier weight class. The majority of students
were out of luck now since we were too big for the remaining glider.
It was getting late anyway, and many students were waiting out their turns
and letting the more enthusiastic folks like myself go again in their place.
Now with the majority of the students grounded and generally exhausted,
we had to call it a day.
After we packed up the gliders, Bruce talked
about the options for continuing our instructions such as where we might
take additional lessons and/or taking tandem flights where a student and
instructor fly together in the same (albeit oversized) glider. He
pointed out that, no matter which path we chose at this point, we weren't
the same people as we were before that weekend's experience.
He was right. As enthused as I was
before taking the lessons, I was absolutely obsessed in the weeks that
followed. Every hill I passed, I pointed out to Dani and said, "That
would be a good one to train from!" I continued researching flying
and made contact with the local glider community. Dani and I recently
purchased our own glider, so we're committed to following through on this
adventure in the making.
Flying is frustrating at first, and at
the end of these first two days of lessons, all of us were sunburned and
sore in more places than I could list, but there's a little bit of reward
in each incremental advance between being stuck on the ground to flying...
if only for a few seconds at a time. I guess it would be corny if
I start pulling puns about getting "high" here, but you can't help but
sound trite when you talk about something this uplifting. Damnit.
I did it anyway.
