Narrative:BEA Flight 142 was en route from London to Naples flying on Airway Amber 1, reporting over Ostia at 23500 feet at 11:44. The flight reported continuing to Ponza, estimating arrival over this NDB at 11:57. At 10:45 a formation of 4 Italian Air Force North American F-86E Sabres had taken off from Pratica di Mare Airport on a group tactical training exercise in the Pratica CTR (West of Amber 1 airway) which was prohibited for civil aircraft. The formation was 5km E of Anzio on a 310deg heading carrying out a reverse attack manoeuvre consisting of an initial dive, followed by a climb turn to the right and a steep dive with final recovery to level flight. During the steep dive that followed the climbing turn, the leading aircraft collided with the Viscount. Both aircraft crashed, but the F-86 pilot was able to eject.
PROBABLE CAUSE: "The accident was attributed to "an Act of God" - since neither of the pilots saw the other aircraft before they collided.
A contributory cause of the accident was deviation of the Viscount from the airway which placed it in a prohibited area reserved for military activities."
