Personaaly noticed at Khartoum, some years ago, parked on the ramp.
An Ethiopian B727, that suffered a birdstrike at 4000agl, while doing 340 KIAS.
The bird ( a big buzzard I think) went thru the radome, forward pressure bulkhead, broke the First officers left leg, went thru the FD door, and what was left of the bird was splattered all over the first class lounge, just aft of the forward galley.
Not a pretty sight.
Leave the fast below 10 to the military jet jocks.
