A camera drops from an airplane while recording and meets an unfortunate fate.

Based on the footage, it appears that the camera dropped out of the airplane and fell for an extended period of time, before finding a new home in YouTube user Mia Munselle's pig pen. She claims to have found the camera eight months after the fall, which is when she reviewed the recording and uploaded her findings onto YouTube.
In a comment, Munselle informs viewers that planes carrying skydivers frequent the airspace above her ranch, so this type of thing isn't as far-fetched as you may think. As for determining the date of the footage, she writes, "we plugged the camera in and the video was date stamped." Luckily for whoever owns the camera, it survived both the impact and the events at the end of the recording.
