Lucky man, I know those doors aren't the heaviest of items, but they could still do some damage.
I know of an emergency window exit being lost from a 101 (the one forward of the sliding door), was a navy variant, and decided to leave the aircraft somewhere over Somerset. Never did find it, some farmer probably has the worlds most expensive shed window now. Gave the guy sitting in the instructors seat a shock as the window next to him left the aircraft.
