Never mind about the piloting aspects of this accident, what about the bird strike capability of the engines? Big flocks of starlings are very common indeed, and brought down the Electra at Logan many many years ago.
Regulations were improved such that starlings were no longer perceived as a threat, and we had moved on to address Canada Geese!
Bird Requirements probably need revisiting. Is the AIA database still in place?
I believe that the regulation update addressed the fan damage from big birds. I don't think that they recognized a threat from extreme quantities of small birds in the data base. The Electra is a very old accident and while birds were involved I don't think that it is directly comparable with this incident
OTOH I haven't seen any photos of the engines showing damage, just a rumor a few posts above about the Mods editing out the photos of damage.
