To die in a helicopter crash, or other unsafe vehicle with useless safety protocol. With or without knowing that is a serious
possibility when taking flight in a metal can made airborne by giant samurai swords of death and really useless emergency protocols when a crash is imminent. ALWAYS check that your chopper has the proper "Oh Shit!" handles located in convenient, easy to access locations.
Personally, I believe they do actually help. Not as much as prayer though
of course.
