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.
How did high power lights even damage the windows so badly that they are literally missing?

"The lights, which were intended to give the illusion of a sunrise, were placed about 20 to 30 feet from the aircraft, shining on first the right, then the left side of the craft for over nine hours in total.
A foam liner had melted away from at least one of the windows and several window panes appeared to have been warped by the thermal heat. "
