Here's a Q for everyone in the brain trust:
I know the definition of "Bingo fuel", but what's the story behind the phrase?
I've used it for years, but the other night another player asked why it's called "Bingo fuel", and I couldn't explain it. So, what is it? Did the pilots cross out little squaresrepresenting the amount of fuel on their knee board as they went along, and then called out "Bingo!" when they'd crossed out five in a row? Or does it mean "Bad Idea, No Gas Onboard"?
Any help in solving this mystery will be appreciated.
