I developed a phobia about helicopters in the Marine Corps. They kept kicking me out in the middle of nowhere and making me walk home.
Id rather jump into a hot LZ than have to stay on the chopper any day.
(Joke to follow:) I don't know what it is with the Marine's, they always seem to be walking home, after they take care of business.
It must be they have alligator arms, with very deep pockets, when it comes time to put gas / fuel in a vehicle or aircraft.
