Here's something you may not know: tanks are heavy. The guys operating this crane must not have known that, because they tried to lift and move this one at an angle that proved to be too much. Everything seemed to be going smoothly for the first minute of the video, then gravity decided that it was time to teach them a lesson. Watch as the crane slowly tips before it comes crashing down on a trailer nearby. Hopefully there was no one inside at the time.
