Taxiing down the runway, the passenger jet abruptly came to a stop, turned around and returned to the gate. Eventually however, after an hour-long wait, the flight 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.
“I hope it’s all sorted now.” Replied the nervous passenger.
"Oh yes, it’s fine now Sir, it just took us a while to find a new pilot."
