Some pretty pictures of parachutes for light aeroplanes, designed to protect the 'plane (and, presumably, its inhabitants) if something goes Bad And Wrong. There are, of course, certain emergencies for which the parachute won't help. Cf. Philip Greenspun's discussion of what sort of aeroplane you should buy; and something from those nutty guys at Armadillo Aerospace:
I tried to buy a new airplane parachute from BRSI last year, but they wouldn't sell me one after I told them what it was for.
