I'm sure everyone has met semi-trucks hauling large pieces of construction equipment while driving down the highway. Ever considered what would happen if that equipment came off the trailer?
The machine came off the truck to the left, bounced over the barrier, flew over the gap, hit the barrier on the freeway opposite, and landed in the grass below. I don't think anyone got killed but Holy Crap! Can you imagine driving down the road and seeing this unfold!
