In 2007, the hijacking of a Mauritanian flight was thwarted. Over the PA, the pilot instructed the passengers that he was about to make a bumpy landing, and they should attack the hijacker while he was off balance. He said this in French, which the gunman did not speak. The ploy succeeded.
While filming the movie “Entebbe,” about a plane being hijacked, a plane was actually hijacked and landed at the airport. They filmed the real hostages being released and edited it into the movie.
