@cssourceAA: of course it doesn't come out the other side! Planes are lightweight structures made mostly of aluminium, if it collides with a dense steel and concrete structure at about 500mph it will disintegrate on impact. Chuck a few tons of avgas in to the mix and the ensuing explosion will on...
The 'mud run' is just for fun. It's not part of the course. USMC wouldn't know what to do if their helicopters broke, TAB?? What's that?
Watched 'One Man Army' on Discovery last night. Some Delta Force guy got whooped by a gay bloke.
