If you want Felix I can ask the guy.. he's one of my fellow student colleagues at Embry-Riddle. Called me on that day and was like, "Hey you know what, I got almost run over by a Beaver." I thought how can he get run over by a Beaver (animal).. He also pointed out that in the video you see a small dust cloud in the grass, where the left wing hit the ground, like 3m (10ft) away from him.
Best regards,
Phil
