A plane suddenly loses one of its engines

“This is your Captain speaking. I’m afraid we have lost one of our engines so we’ll be about 10 minutes late arriving at our destination,” announces the Captain. “Oh no!” Says a passenger. Then suddenly, another engine fails. “This is your Captain speaking. I’m afraid we have lost another one of our engines so we’ll be about 30 minutes late arriving at destination,” announces the Captain. “Another one?” The passenger says again. Suddenly the Captain says, “This is your Captain speaking. I’m really sorry to say but we’ve lost a third engine so we’ll be a bit more than an hour late to our destination.” “I hope that fourth engine doesn’t fail our we’ll be up here for the rest of our lives!” Says the passenger.
