You say that as if a twin engine plane is safer. Twin engine airplanes should be treated the same as a single engine aircraft. Most small twin engine airplanes typically cannot fly efficiently with a single engine if you have passengers and/or cargo. If you have two engines, you double the chance of failure.

A bit of risk, but huge rewards. Little planes actually glide quite well, so with some altitude it's often possible to make an uneventful landing where the plane is bent but the people are fine.

The future is airplanes that have parachutes (for the plane itself). There is a prototype in x-plane. If that's the case yes I would.

Why not? A helicopter is even more dangerous than a plane anyway and there are millions of flight hours every day, safely.

Would you let everyone live on a single planet? I know I wouldn't. Talk about throwing caution to the wind.
