Interesting stuff. A Dash 8 was nearly written off in Australia some years ago. It was on descent when a large eagle with the best part of an undigested rabbit in it's gut struck it on the wing leading edge near one of the engines. The bird actually pieced into the wing structure and severed some of the engine control cables and wiring. Forced an engine shutdown and assorted mayhem. I can't recall exactly but the aircraft was a bordeline write off due to the amount of damage and fears over a bent wing spar too. I admit he was probably pulling the scales down more than 2.2 pounds but the damage was massive.
Must be nice to hit one in a fast jet at 500 knots on the deck.
