"The most important wings on an airplane are on the pilot."
---T. Allen McArtor
Here's another quote I hate. I hate it because if you think it through, it's wrong!
If I'm on a plane, and the flight attendant comes on the PA and says, "We have a problem. The pilot has suffered a sudden heart attack," there's still hope that someone else on the plane has some flying experience, or ground control can talk a brave person through landing the plane, or both, as in Airplane!
If I'm on a plane, and the flight attendant comes on the PA and says, "We have a problem. The plane's wings have fallen off," I think we're pretty much screwed.
