A pilot for British Empire Airways is found to be at fault for the death of his co-pilot after the crash of his jetliner at takeoff. But when a fellow pilot later dies under similar circumstances, the question arises: are the crashes the result of human error, or has the aircraft's manufacturer made a grave mistake? Released in America as TROUBLE IN THE SKY, Charles Frend's CONE OF SILENCE stars British film legend Peter Cushing (STAR WARS) in a rare villain role alongside George Sanders (PSYCHOMANIA), Michael Craig (TURKEY SHOOT), and Bernard Lee ('M' from the James Bond films).
