This guy in Oregon avoided a tragedy narrowly when he walked into a convenience store, just before a runaway blade smashed into the building.

Shane Reimche just made it inside unaware that a huge runaway saw blade was barreling across the parking lot and smashed into the building right where he had walked by.  The blade shook the whole building. Turns out, the runaway saw broke loose from a construction site up the road.
