That film is rather interesting. After looking at it over and over it's hard to tell who's at fault.
The HUD symbology actually says alot though. Well I know for a fact he was in boresight mode, AIM9 selected as primary, he was doing 340 kts and he had to have known where his con was headed.
That white blotch that you see right of center is his seeker head position symbol. You can also hear the AIM9 growl in the audio. He did have his Target aspect angle symbology which should have told him right off the bat they were currently at a path inwhich they may collide. His A/A target designator also told him the relative position of the contact when it went out of view. Coupling this symbol and his Target aspect angle symbol he should have called knock it off when they were that close. Considering one was telling him that the contact would be coming up and to his 10 oclock position on his HUD and the other specifically showed that the con was below him.
It's easy to say this after looking at his video but their closure rate must have been extremely high and it would have been a cat like reaction to avoid this. The problem is he didn't go to his first detent on his trigger until they were extremely close. Had he started his recording earlier it may infact show that they pushed too hard during the engagement and made the collision course inevitable. Either way sounds like he may have survived. He was concious after the collision and calling mayday.
