The Noisy Engine

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.
