With Helicopters in OFallon, MO Safety is Everything:

People fly helicopters into friends' backyards, onto highways on rainy nights after car accidents, onto rooftop helipads, and with air conditioners hanging underneath. Helicopters are unstable and very few are equipped with autopilots. You'd expect helicopters to be vastly more dangerous than airplanes. They are and they aren't. Big jet-powered helicopters are safer than small airplanes, but not by the huge factor that big jet-powered airplanes are safer. The jet-powered helicopters suffer 4 accidents per 100,000 hours, 1 of which will be fatal. Piston-powered helicopters, which these days means Robinson suffer 13-20 accidents per year with roughly 2 of those accidents being fatal.
