Неизвестно, обычно в буржуазных источниках пишется просто "SAM or AAA hit".
Вот что пишет тот же небезызвестный Том Купер (типичный образец):
"What exactly happened to Karma 52 (F-111E 70-2385) remains unclear: the plane apparently dropped its bombs precisely, and flew with the others in formation for some 30kms away from Tripolis, when other crews - and, reportedly, the crew of one or two Tomcats which waited for them - noticed a fireball over the sea surface at 00:10. There are different theories for the loss; including AAA, SAM, and even a fratricide shot from one of F-14s. Certainly, the crew, Capt. Ribas-Dominici, and Capt. Lorence, was killed. Autopsy of Ribas-Dominici (his body was returned by Libyans years later), showed that he drawned, possibly still inside the capsule (the F-111F has no ejection seats, but the whole cockpit is ejected from the rest of the plane)."
В этом тексте у Купера ошибка в отношении самолета - на самом деле потерян был F-111F с\н 70-2389, а самолет с\н 70-2385 (который тоже "F", а не "Е") вообще в "Eldorado Canyon" участия не принимал и был благополучно списан 13.11.1995.
Вот здесь есть некоторые детали гибели и выяснения судьбы экипажа - но тоже никто точно падения не видел:
