Remember, we are told statiscally a double engine failure is impossible,
You may have misunderstood
A double engine failure has a probability of 1 in a million for all causes and and 1 in 10 million for other than crew error causes. It's only statistically improbable against independent causes that a lot of pilots seem to worry about while dozing for dollars
(tongue-in-cheek mode)
Sully demonstrated that it is entirely possible to survive with a double engine failure.
But back to the subject event.
After seeing the pics, this was an extremely close call. I'm afraid that a very bad result would occur if this gets repeated at V1+ You are correct in that the engines and aircraft are not designed to accomodate running into a flock of geese at V1+ whether twins or quads so a large ounce of prevention, avoidance etc. must be regulated.
The issue in this case appears to be an airport bird flock on the runway ala Elmendorf etc.
The pilots must report flocks of this type directly, if seen on the ground, and the airport authorities must take immediate action to close the runway until the birds are moved.
I'm not sure why this event happened or where the loophole is.
Did any crew actually see a flock of geese on the ground near this runway that day and did they report the same? I hestitate to get into the subjectivity of transient bird flocks on the move, but this flock appears to have been on the ground and on a runway.
