Buster, in fact all the ones cited so far occurred in the departure phase, including the Su30, where we could expect the engines to be at full power hence full suck.
I would imagine the wrong scenario with a canopy strike as well as engine ingestion. Pure speculation, but if you suffered a canopy strike would you be able to recognise catastrophic engine failure at the same time? Could the catastrophe be such as to cause brain stall that inhibits the eject response?
