Doesn't there come a point where you stay home if you can't trust the primary structure of your flying machine?
Stated another way:
Assuming that the parachute for the aircraft weighs 150 lbs (a real challenge) how much stronger and safer would the rotor be if you put that weight into the helicopter to make it stronger and safer to begin with?
Or a third way, If the spare tire in your car cost you a passenger would you carry one?
