i think su 30 mki needs two pilots for carrying out all sorts of operations while F-16 B does not need two pilots. it is just for training of new pilots. it has similar capabilities as compare to single seater other then less internal fuel storage. the narrative of locals about three pilots ejecting further supports the fact that india lost one mig 21 with pilot landing in azad kashmir while the two sukhoi pilots landed inside IOK. PAF is not stupid enough to send two pilots in F-16 B when it is not needed at all.
it seems both the jets are JFT and the video is old. why JFT was just racing with su 30 . it should have launched BVR or WVR missiles as missiles are much faster then the jet.there was no use chasing the jet and escorting it till LOC.
but today's statement of modi regarding rafale jet shows that IAF has lost the aerial engagement with PAF and they have also lost confidence in their premier air craft su 30 which indians used to consider as the best fighter jet in the world.
