This is a video of the guys from Youtube channel FliteTest attempting to trip an AT-AT model they built using a snowspeeder drone and tow-cable. In the end, they are able to successfully bring the AT-AT down and buy enough time for the Rebel Alliance to evacuate Echo Base and flee Hoth, presumably leaving Darth Vader standing in the cold with his badly burnt penis in his hand.

Keep going for the video, with actual flying beginning around 12:30, and the tripping not until 15:10. Everything prior is just building the AT-AT model and toying around with the drones.
