Trying to focus back on what
@patriots had posted earlier about the f-16.net forum discussion.
I didn't see Tom Cooper say that F-16 went down, but it did appear that Mig-21 surprised the F-16 and came in from height of 13000ft compared to 7000ft where the F-16's were.
This is what Tom Cooper had said

They're going to do so, whether the Pakistanis like that or not. The reason is that Pakistan is obligued to let the Pentagon (and LM) inspect their F-16s at least two times a year.
A slightly different question is the one of what are the Pentagon and LM then going to release about their findings. If one has nothing else to gauge upon, when a PAF F-16 got shot down back in 1987 (yes, my memory happens to go that far back) official Islamabad first said that none was lost - and then maintained that version for about two months, before coming out with the version about 'fratricide fire', and that with help of same people (then working for General-Dynamics, later for LM) who also helped convince the Pakistanis their F-16s shot down 'two Soviet MiG-23MLs' (actually, they damaged one).
What a surprise then, the case is actually unclear until this very day....
Well, sorry to inform you that in the case of Pakistan, this can easily take 50-60 years.
Just one example: official PAF still insists on M M. Alam shooting down '5 Hunters in less than 5 minutes', back in 1965 - no matter how much this was proven to be a lie, and that already 20 years ago.
There was no 'dogfight' on 27 February.
The PAF was 'orbiting' on one side of the LOC, the IAF on the other. Then the PAF found an opportune moment: Su-30MKIs were heading in opposite direction (one can't orbit in direction of the opponent all the time), and it appeared to the Pakistanis that nobody is airborne over Srinagar. So, they sent 4 F-16s 'in'.
As these 4 F-16s moved in, the Su-30MKIs turned to intercept, in turn prompting the other 4 F-16s to engage them. That's how it happened few AIM-120C-5s 'migrated to India'. But, since AMRAAMs were fired from 30km+ away, all missed (about 10+ years ago, when some really well-informed people were still finding it worth to frequent places like this forum, one could still read why:
viewtopic.php?f=2&t=6302&p=75873&hilit=Looks+like+I%27ve+yanked+your+chain#p75873).
Furthermore, the problem is there's a mountain chain with 4,000m (that's about 13,000ft) high peaks in between the LOC and Srinagar. Thus, the PAF AWACS missed the IAF scrambling several MiG-21s from Awantipora FOB and Srinagar AB in response to ingressing F-16s. Yes, ladies and gentlemen: contrary to video games, in reality radars can't see through mountains. First surprise here, I guess.
So, when the MiGs climbed over that mountain chain... 'surprise, surprise': they found themselves at 15,000ft+ - high above F-16s that were ingressing at about 7,000ft. The lead MiG dove, ignoring the fact he's crossing the LOC while doing so, one of F-16s came up towards the MiG. What happened next is unclear.
...that is: until the moments captured on several cell-phones, showing that MiG going down in flames.
Where have I got this? Call it a 'rumour'.
