Don’t get lost
 

The pilot sat up in his seat and casually pulled out a 38 revolver from his flight bag:

He placed it on top of the instrument panel, and then turning to the navigator asked. "Do you know what this is for?"

The navigator nervously replied. "No, what is that for?"

The pilot responded. "I use this on navigators who get me lost!"

The navigator nodded and proceeded to pull out a .45 and place it on his chart table.

The pilot asked. "What's that for?"

"To be honest sir." Replied the navigator. "I'll know when we're lost before you will."
