I never said soaring was perfectly safe. I wouldn't say that, because
I'm pretty sure it's not true. All I asserted was that BASE jumping is
less safe than soaring in terms of per-hour or per-cycle exposure.

If you can cite peer-reviewed statistics that demonstrate otherwise, I
am certainly open to changing my mind on this.

Thanks, Bob K.
Please get your story straight and don't post drunk.

Some-one posting playing silly buggers.

George,

don't you have to run and hide from an in-coming asteroid?

better run along now and let the sailplane guys argue about sailplane
stuff, leave the base-jumping topics to a relevant forum.........ok?

Jeb Corliss is not just flying over terrain that is declining at

True, he is apparently deliberately diving faster that his best L/D
speed. *This maneuvers him down towards the rock face while at the same
time allowing him sufficient kinetic energy to escape the declining
terrain by simply pulling up.

What appears to me to be the
very difficult part is that he flies within 10 feet of the ground.

One could argue if that's difficult or simply foolhardy. *I will agree
that it's probably difficult to do it regularly without finally having
an accident.

What appears to me to be
unusually difficult about his stunt is that he has no escape
route.

Not necessarily true if he planned the stunt correctly. *As long as he
maintains sufficient maneuvering energy and the terrain keeps moving
down rapidly, all he needs to do is pull up. *He will simultaneously
slow down and move away from the rock face. (Trading kinetic energy for
potential energy) * (See above.)

It was interesting (to me) to note that the injuries sustained in his
cliff strike were to his legs and feet. As a former sport skydiver I
suspect this was a near miss (in the true meaning); in order to obtain
lift while flying, you must reverse arch to form a curve/lifting body
with your body. Since the wingsuit extends to include the hands/arms
and legs feet, one would have to include the feet as the tail/low
point of the arch.

I suspect he saw he was going to be low and hard arched, which saved
him from a collision with his body, but caused an impact with his
feet.

BASE jumping wasn't on my list of things to do and I left the sport
after 'only' 937' jumps. It became (I was primarily a freefall
videographer/photographer) just another weekend job....and that leads
to complacency which leads to injury.

You are wrong. *Aviation or at least commercial aviation is inherently

I don't necessarily agree with that. The phrase I use to describe
aviation is "statistically safe, but inherently unforgiving."

To me, the phrase "inherently safe" refers to an activity that has few
if any operational modes where constant alertness and engagement is a
prerequisite for continued survival. I think that something is
"inherently safe" when you can turn your back on it, go to sleep, and
expect to wake up an hour later in good health. That covers the vast
majority of aviation passengers, but certainly not pilots. As the old
joke goes, I want to die in my sleep like grandpa, not screaming in
terror like his passengers.

Thanks, Bob K.

That's a reasonable clarification Bob. But I'd also argue that the
universe is constantly in opposition to your definition. After all,
there are comets, asteroids, etc. out there with our name on them.

What part of wing suit eluded you ?
It's still flying

Brilliant!

PS. Jeb was trying too hard. You can get that amount of adrenaline just
being a passenger in a minibus taxi in Cape Town...

I think it's the first time a wing suit flyer has struck an
earthly object and lived. No doubt the first time it's been
filmed. I am amazed that he was able to open the parachute before
striking the ground. That is as close to dying spectacularly as
you can get.

Suggesting a hint of bravery and good sense go hand in hand when hand

If by "absconded from" you mean "stole," (which is a sense I've never
encountered), you should know that Lee was 64 the year McKenna was
born. I assume you were just trolling but it worked out well for me
because I'd never read about Lee before. So, thanks.
