Crew aboard a U.S.-bound plane discovered a missing window pane at 13,000 feet

A U.S.-bound plane took off from London last month with four damaged window panes, including two that were completely missing, according to U.K. air accident investigators.

No one was injured by the window malfunctions, which appear to have been caused by high-power lights used in a film shoot, the U.K.’s Air Accident Investigation Branch reported in a special bulletin published Nov. 4.
