Mouse delays flight from London to San Francisco

A mouse flying from London to San Francisco delayed the flight for four hours in order for the human passengers to board a new plane.
According to the Associated Press, the crew told travelers they couldn’t take off and joked that the mouse needed a passport to enter U.S. airspace. Despite the delay, it was reported the most of the passengers were glad to be on a mouse-less flight and British Airways apologized as soon as the late flight took off.
