Goog luck trying to hear an ejection seat from at least 10,000 feet. People are interpreting some random street noise as ejection seats.
The video was obviously of the Mig-21 that was shot down over the Pakistani side. Basic logic says if it was an SU-30 then it would have also crashed on the Pakistani side. So where is it? Where are the photos or at least eye witnesses account from either side of Indian pilots/debris? Not even a smoke plume.
I don't think any other aircraft was shot down but bassed on the video evidence, Indian claims. if I were to choose who lost what I would say it is far more likely a twin seat F-16 went down then an MKI.
