I hate to be a party pooper,
BUT..... I can't help but wonder how it is that BOTH engines were so badly damaged by bird ingestion that they could not continue to fly. I don't believe this has ever happened before. Has it?
Does anyone else besides me consider that maybe this crew screwed up? Maybe they actually shut down the good engine during a severe damage engine shutdown while attempting to return to the airport.
At low altitude there would have been no time to restart it.
