Investigation Summary
The accident occurred within the Pratica di Mare Control Zone (CTR), an area strictly prohibited to civil aviation. BEA Flight 142 had reported its position over Ostia at 11:44 GMT (12:44 local) at 23,500 feet and was expected to proceed to the Ponza NDB. However, the aircraft deviated from Airway Amber 1, entering the military range where four F-86E Sabres were conducting a 'reverse attack' exercise. This maneuver involved a dive, a climbing right turn, and a subsequent violent dive. The lead F-86, piloted by Captain Giovanni Savorelli, collided with the Viscount during the final dive phase. The impact sheared a wing from the Sabre and compromised the Viscount's pressure hull, leading to immediate structural failure. While the F-86 pilot survived, sources conflict on his escape: some records state he successfully used his ejection seat, while others claim he performed a manual bail-out after the canopy was lost. The Viscount plummeted into the military testing grounds, leaving no survivors. Investigators noted that the high-speed, high-angle nature of the military maneuvers made it virtually impossible for either crew to see and avoid the other in time.
Final Conclusions
The official investigation attributed the collision to a 'tragic fatality' (Act of God), concluding that neither pilot could have seen the other aircraft in time to react. A significant contributory factor was the Viscount's deviation from its assigned airway, which placed it directly in the path of military aircraft performing high-speed tactical maneuvers in a restricted zone.
