Helicopters are subject to single failures causing a fatal crash. Hence helicopters rely heavily on rigid, thorough, and very expensive maintenance.

As my dad (combat pilot) said, an airplane wants to fly. It can suffer considerable damage and still make it home. A helicopter, however, wants to crash. It's a constant struggle to keep it in the air.

I've never ridden in a chopper, but I doubt I'd feel safe in one.

I've never worked near helicopters, but they went on my "never take a job anywhere near these things" list after the third time I accidentally stuck my hands into the whirling blades of the ceiling fan in my living room.

I once had a chance to take a job related to navigation. I got significantly lost on the way to the interview. The job didn't work out, probably for the best.
