It was IDF. When I was stationed at Elmendorf there was a 15 that got shot by another 15 with an AIM-9. Took off the left horizontal stab, half of the left wing, and FOD'd out the left engine. It flew back to EAFB and landed fine. The fuselage is a lifting body itself. This incident happened before I got there, but the whole story and photos were posted on the wall in Hanger 4 there.
