A loosely related story...
In about 1986 we sent a helicopter from Fort Erie far into the Great White North for cold starts. On the way home, the rear hatch opened in flight. The pilot was able to set down quickly, and the only thing not found was a nice metal case containing the company 35mm camera.
About 4 years later, we received a large package from an RCMP detachment in Northern Ontario. Inside was a dented metal case with the company camera, a package of prints (including several that clearly showed the registration and the big back doors on the BO105), and a hand written note saying we should be more careful about closing that rear door.
