Trans World Airlines Flight 840, registration N54340, was a Boeing 727-231 flying en route from Rome's Fiumicino Airport to Athens. A bomb was detonated on the aircraft while it was over Argos, Greece, ejecting four American passengers (including a nine-month-old infant) to their deaths below. Five others on the aircraft were injured as the cabin suffered a rapid decompression. The remaining 110 passengers survived the incident as pilot Richard "Pete" Petersen made an emergency landing.
