Well thats easily verifiable. You all seem to forget, the PAF F-16s are frequently inspected and attended to by American personnel to ensure that no component or weapon makes goes missing only to turn up in CAC. So if the US hasnt been talking about it, then its likely not true. More likely the Parachute was that of colonel Abhi.
As for having AIM120 wreckage, highly unlikely that it left identifiable wreckage, but if it did it would have landed in Pakistan, because IAF only lost one aircraft to PAF remember? Isnt that the official line of Gov of India? But if colonel Abhi was shot down over Pakistan, any missiles remains wpuld be in Pakistan far from Indian reach. IF you have missile wreckage in India, youust admit a second jet went down which begs the question which aircraft and who shot it? I am of the question that it was more likely a Mig, and likely by the same type that took the colonels plane. This is likely JF-17 as the pilots who were credited are thunder pilots.
