We are not interested in rest of the three missiles.
Abhinandan's last recorded voice was ' R-73 selected'.
you can see Pylon rail of right side R-73 is completely visible in the wreckage and damage it is least compared to other parts. When damage to pylon is this low what's chance of missile getting severed from it.
If you say, there R-73 parts must be lying around nearby the wreak, there is this a bigger video of the crash site below, here too there no sign of R-73 parts that were recovered by Pakistan and put on display for everyone to see. If you still see one, point it to me.
