May I? EggsAckley!
I am going to say, due my experience, I'm sceptical that birdstrike(s) could cause that type of catastrophic failure to not only the motors, but also the airframe. Tails, wings, and motor mounts are constructed pretty robustly.
When there are aircraft crashes, the mjority of the plane stayts together until impact.
Ditto.
Another Eggs "fact?" Many posts--including your own--on this thread scoffed at the idea that a birdstrike could bring down an aircraft.
