In the 1980s the RAF lost quite a lot of Harriers to low-level bird-strikes.
Steve Belcher, a colleague and good friend of mine, died in the post-takeoff crash of his Nimrod. They found 70 or so dead seagulls on the runway; 3 out of 4 engines had lost power due to birdstrike damage. He, as co-pilot and the captain were both killed but everyone down the back survived the crash into the forest off the end of the runway. RIP, mate.
