A lot of the reports about the pilots being killed claimed they were killed because they didn't eject, but looking at those pictures, that clearly isn't so. I am more and more inclined to think the KIA reports are just rumours, and wrong at that.
It would be extremely unusual for pilots who had ejected at a reasonable altitude to be killed by the ejection process. The vast majority of ejection related fatalities involving modern ejection seats happen because the pilots ejected too late/low and their parachutes did not have time to deploy fully. Had that been the case, the eye witness reports would have said the pilots died because their chutes did not open rather than because they did not eject.
I am thinking that the 'did not eject' story came about because the people who witnessed the crash did not see parachutes and assumed the pilots were still onboard. But from those pictures, it is clear that the pilots did eject, and if they did so early enough that eye witnesses who saw the plane come down did not see the chutes, then there is a very good chance they ejected high enough for their seats and chutes to deploy properly, which would give them a very good chance of survival.
