How difficult, Jeb Corliss wing suit stunt?

Jeb Corliss is not just flying over terrain that is declining at
least as fast as his descent rate.

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.

Mainly curious about how difficult that was.
Thanks.

After viewing it and the runup to it, it's not a stunt that is
that life threatening. He had a whole group of experts to help
him all along the way. They knew, with certainie, that it would
be successful. NO errors could be made though which could have
had disastrous affects. He didn't make any and it was successful.

I note that many of have stated that he is more than a little
nuts. Not in this case. He is a craftsman and surrounds himself
with other craftsmen that makes what appears to be impossible to
be possible.

You do know that he had to be airlifted to hospital last month
after one of his carefully crafted stunts went wrong.

As the saying goes "**** happens'

People walking across streets get hit by buses.
Painter falls off roof
BASE jumper hits something on the way down..
Little old lady slips in street and breaks her neck of femur..

People walking across streets get hit by buses.

Usually as a result of not looking before they step off the
footpath.

Painter falls off roof

Usually because they are not using properly secured scaffolding

BASE jumper hits something on the way down..

As a result of taking an uncessary risk - there seems to be a
pattern developing here.

Pot meet kettle. US glider pilots aren't in a statistically sound
position to criticize BASE jumpers right now...

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.
