Blonde's Flight Across Atlantic

A blonde is on a four-engine plane crossing the Atlantic. All of a sudden there's a loud bang. The pilot announces over the intercom "I'm sorry, one of our engines has just shut off. We'll be delayed 45 minutes." Suddenly there's another bang. Once again, the intercom clicks on and the pilot expresses his regret that they'll be delayed two hours. Shortly thereafter, there is another bang and the pilot announces that they'll be delayed 3 hours. The blonde turns to the guy sitting beside her and says, "Man, if the fourth engine shuts off we'll be up here all day."

Polish Airplane Boom

A Polish man was taking a flight on a commercial airliner. The airliner had 4 engines, which is quite normal. About an hour into the flight, a loud BOOM occurred. The flight attendant came over the intercom and said, "Ladies and gentlemen, we have blown an engine, but there is no need to worry. We still have three engines, I repeat, we still have three engines." Everyone stayed calm. About another hour later, another boom. The flight attendant comes over the intercom. "Ladies and gentlemen, we have blown another engine, but there is no need to worry! We still have two more engines to go!" The people stayed calm. An hour later, the same situation. Now only one engine remained. Then, the Polish man stood up and said out loud, "Man! If this keeps up, we could be up here all day!"

Flight Risk

A mathematician and a non-mathematician are sitting in an airport hall waiting for their flight to go. The non- has terrible flight panic.
"Hey, don't worry, it's just every 10000th flight that crashes."
"1:10000? So much? Then it surely will be mine!"
"Well, there is an easy way out. Simply take the next plane. It's much more probable that you go from a crashing to a non-crashing plane than the other way round. So you are already at 1:10000 squared."
