Nothing sturdy at all about planes. If you need the strength maximums and such of planes, you'd never probably go on one.
My neighbor use to work making planes and is a plane freak of sorts. The horror of the stories, and he likes planes...
I love flying. Always wanted to get my pilots license. I've even been on a commercial flight that was forced to 'crash land' in Dayton, Ohio instead of Indianapolis. Flew later that week again too. Put me in a car on the interstate though, I'm tense and nervous as shit.
Unfortunate accident though, though most cases in small planes you
can survive (unless you nosedive right into the ground or land in a house). Every 10 miles of US interstate has 1 mile of straight road in the event a plane ever needs to crash land and needs to use the interstate as a last resort. Bring that baby down in a cornfield or in a river. My ex's cousin and her dad were out flying in a little two seater Cesna a few years back, engine failure, crash landed in the Ohio river, she stubbed her finger and had to wear a brace on it. The Dad I think came out without a scratch.
