Taxiing down the tarmac, the jetliner abruptly stopped, turned around and returned to the gate.

After an hour-long wait, it finally took off.

A concerned passenger asked the flight attendant, "What was the problem?"

"The pilot was bothered by a noise he heard in the engine," explained the Flight Attendant, "and it took us a while to find a new pilot."
