Military Aviation Humor

I heard this from my brother, who is a Search and Rescue pilot at Canadian Forces Base Bagotville, Quebec. It's an apocryphal story that allegedly happened late one night during
bad weather, as heard over the tower radio:

Helicopter Pilot: "Roger, I'm holding at 3000 over (such-and-such) beacon".

Second voice: "NO! You can't be doing that! I'm holding at 3000 over that beacon!"

(brief pause, then first voice again): "You idiot, you're my co-pilot."
