A couple of aircraft jokes:
The pilot was sitting in his seat and pulled out a .38 revolver.
He placed it on top of the instrument panel, and then asked
the navigator, "Do you know what I use this for?"
The navigator replied timidly, "No, what's it for?"
The pilot responded, "I use this on navigators who get me lost."
The navigator proceeded to pull out a .45 and place it on
his chart table.
The pilot asked, "What's that for?"
"To be honest, sir," the navigator replied, "I'll know we're
lost before you will."

"Flight 2341, for noise abatement turn right 45 degrees."
"But Center, we are at 35,000 feet. How much noise can we make up
here?" "Sir, have you ever heard the noise a 747 makes when it hits
a 727?
OK Center, 2341, we are turning! We are turning!!
