Joke: Assistance-Fool joke

While practicing auto-rotations during a military 
night training exercise a Huey Cobra screwed up 
the landing and landed on the tail rotor. The 
landing was so hard that it broke off the tail 
boom. However, the chopper fortunately remained 
upright on its skids, sliding down the runway 
doing 360s.

As the Cobra slid past the tower, trailing a 
brilliant shower of sparks, this was the radio 
exchange that took place...

Tower: "Sir, do you need any assistance?"

Cobra: "I don't know, tower, we ain't done 
crashin' yet."
