Apparently the loadmaster on a USAF C-130 was invited to take the engineer's seat for a while. He started jabbering away, not realizing that he was trans-mitting on Uniform instead of over the ICS:
LM: "Hey, this is great! I see why you engineers like this seat so much -- you can see
everything from here! This is just like the starship Enterprise! All ahead, Mr. Sulu, warp factor ten!

Followed shortly afterward by:
ATC: "You wanna get back on intercom, Captain Kirk? You're transmitting on my frequency!"
