A change was made
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, and wouldn’t fly the plane, until the problem was corrected,” he explained.
“And it took an hour to correct the problem?” the passenger asked.
“No,” the flight attendant replied, “It took an hour to find a new pilot.”
