Several years ago, I was camping at Sun'n Fun, right off the end of the runway.
They had one B-17 on display down there that year. About 6:30, that sucker went
overhead about 500' up on takeoff. Hell of an alarm clock!

Some people think they hear a call to the priesthood when what they really
hear is a tiny voice whispering "It's indoor work with no heavy lifting".
