At best we have a strong circumstantial evidence, handed to us by stupidity of Pakistan. Its a shame that we have direct evidence but not revealing it.
Let us list The Circumstantial Evidence and Actual Evidence in A Chronological Order ( Chronology is the favourite word in India at this time )
1. Abhinandan saw the R 73 hit The F 16
2. Multiple reports of "Do Pilots " / Doosra Banda by Pakistani civilians who lynched their own pilot -- those videos still exist
Abhinandan was running for 45 minutes from the Crowd till he was captured
3 . Ghafoor' s Gaffe in a PC
Where he said " Do Pilots " and
Injured pilot sent to CMH Hospital
4. Then they said we have only one pilot in
Custody -- having realised that he was their Own
Then PAF launched CSAR helicopter because they were looking for their own guy ,When One F 16 did Not come back
5 . RADAR images on the Ground and AWACS by Indian Air force
6. Indian Forward troops having Radio Intercepts confirming Pak Army Chatter
7 . Multiple Twitter , Facebook posts by Pakistani people including one on PDF that Pilot in CMH died
8 . If you have seen Sameer Joshi's analysis , then they have even analysed the different Videos and proved they are 2
Different Material Objects
Now these are what we Know
And be Rest Assured that Both US and Indian Intelligence have sufficient resources in Pakistan to know the truth
My belief is that US has asked India not to further push this issue since it involves an American Fighter Plane
