Surely we should be asking why so much engine damage was done by an encounter with a flock of birds. Flocks of gulls are not uncommon.
And the more curious of us will ask what the results of the engine bird ingestion certification tests looked like, and whether they match current knowledge of the bird threat.
If I remember correctly...
And please feel free to correct me if I am wrong - not the first time, won't be the last....
The test is not for whether the engine will survive an encounter with a bird and keep on ticking in one piece, but whether, upon encountering said bird, there is an uncontained blade failure or not.
The last thing you want is ruptured fuel tanks with bits of (hot) engine sticking out of them or ruptured SLF with bits of (hot) engine sticking out of them.
