Sounds consistent with a "passive" impact (my term - not based on any engineering), I.E., impact with an object with a speed low enough to be considered negligable compared with forward speed of aircraft. Any kind of hard object such as a missile in flight might have done a lot more damage, even if it were a dud.
Experiments with frozen birds launched into aircraft structures have shown significant damage from hard impacts, but I don't know about the results of "soft" or thawed critters.
LOL at thawed critters.
Thank you for the explanation.
