 The video here is pretty long and mostly consists of a burning truck. Apparently the truck deployed it's crane boom and the wire of the crane hit crossed two power lines. I don't see any people near the truck but there are a few people running around in the background and by the road. Throughout the video there is electricity arcing down the stablizers that the crane has deployed. The front of the truck where the engine is located is on fire. Towards the end of the video the wheels are smoking and the front ones are also one fire.
If you never knew why it was a bad thing to cross power lines this might set you straight. Source: Big-boys.com |
