Trans World Airlines Flight 840 was a regularly scheduled flight from Los Angeles to Cairo via New York City, Rome, and Athens. The flight originated in Los Angeles on a Boeing 747 and transferred to a Boeing 727 in Rome for the remainder of the flight. About 20 minutes before landing in Athens, a bomb hidden underneath seat 10F was detonated on the aircraft while it was over Argos, Greece, blasting a hole in the plane's starboard side. Four American passengers, including an eight-month-old infant, were ejected through the hole to their deaths below. Seven others on the aircraft were injured by shrapnel as the cabin suffered a rapid decompression. The remaining 110 passengers survived the incident as pilot Richard "Pete" Petersen made an emergency landing.
