I note SN3Guppy in a previous post recounts his hospitalisation after one particularly unfortunate event, which in itself doesn't act as an advertisement.
That particular jump occured in strong winds in mountainous terrain with a lot of desert plants such as cactus, and the impact point was on a cliff. Not normal conditions for sport skydives, and an unfortunate result of several culminating events which don't need discussion right now.
I've experienced forced landings, inflight engine and equipment failures, aircraft fires, and other inflight and ground emergencies...do these then mean one shouldn't engage in flight in an airplane?
Parachutes fail. Equipment fails. One should still be fully trained in it's use, and this speaks more to a need for adequate training to handle unusual events...a parachute as much as anything else. After all, we don't train for the times things work properly. We train for those times when they don't.
Can you direct us to evidence supporting this "strong suggestiveness" and assertions of "majority being improper use" please?
Yes. Nearly every CAPS deployment in Cirrus aircraft, for starters. That should suffice.
