Ok, so I'm terrified of flying and I just think that planes should have 100% death proof. To me even a 99.9997% is not enough. Sooo, why don't they take some measures like:
1.- Include a huge parachute in case an engine is blown or a wing is blown etc
2.- Make planes so they can glide even without engines (to land)
3.- Special landing site made of special material
4.- Extra wings for gliding
5.- ejection seats
I know some of these proposals would make the aircraft more expensive buut some of them like putting a parachute on the airplane is not that expensive is it??
