I worked for an outdoor equipment company some 15 years ago. We had extreme athletes testing out clothing around the world.
I cant remember the guys name, he was based in DeLand FL, he was (one of, or) the original designers of this flying suit. I have a video of him jumping out of a plane and flying back into the plane, it is real cool (for the times) to see this guy do this. I'll have to see if I can find the tape and post it.
He said he had the glide path of a space shuttle.
He died while working on improvements to the suit.
