Two guys are in an airplane flying at 35,000 feet. Suddenly there’s a loud “BANG.” The pilot comes on the intercom “Ladies and gentlemen, we have just lost one of our four engines. We have three other engines and it is no problem to fly. But we’ll be about one hour late getting to our destination.”
A little while later – another loud “BANG.” Captain comes on “Folks, we have lost a second of our four engines. But this plane can fly on two. But we’re going to be about two hours late getting to our destination.”
A few minutes later, there is another huge “BANG.” The captain comes on the intercom and says “Ladies and gentlemen, I’ve never had this happen but we’ve lost a third of our four engines. This plane is designed to fly on one engine so we’re fine. But we’re going to be about three hours late getting to our destination.”
So the one guy turns to the other and says “Man – if we lose that fourth engine, we’re going to be up here all day!”
