A passenger on a charter flight from the UK to Florida noticed that the plane was missing a window while in the air. The Airbus A321 turned back and landed safely in England, with no injuries reported. Investigators later found that two outer windowpanes were missing, and another outer pane and an inner pane were dislodged. The cabin did not lose pressure during the flight. Passengers reported that the cabin was noisier and colder than usual. It was discovered that the windows had sustained thermal damage and distortion from high-powered lights used for filming on the plane the day before. The investigation is ongoing.
