Apparently, last Sunday a flight due to carry 300 people from New York to London was delayed nearly three and a half hours after a mouse was seen running through the cabin. The crew evacuated and then the captain refused to fly the aircraft, "fearing the rodent might gnaw through some critical wiring and put the entire aircraft at risk." Oh, sure. The wiring, obviously, was the top concern. The screams of EEEEEEEEEEEEEEEE coming from the cockpit had nothing to do with anything.
