Query: Skydiving for the compleat maniac...

Third in a series of textless coffee table books of skydiving photography, published around 1983 and a bit dated now.Still it does contain fantastic photos of stress testing a DC-3, freefall relative work, early efforts at skysurfing and vertical RW, silly stunts that Cessna 152s are *not* certificated for, hoop jumps, round canopies (remember them?), a no-rig jump, China Freefall with the Red Army, Coneheads, nude jumpers, nude jumpers at a nudist resort, masses mooning a DC-3 on takeoff, funnels, El Capitan, Buildings, Night Buildings, The Royal Gorge (if I'd gone along with Robin Heid I'd be in this book) and New River Gorge bridges, Antennas, Balloons, a bunch of bad landings and belly-up planes, and too many vanity license plates. Fun!
