(Eugene, OR) -- A man is lucky to be alive after he narrowly escaped being hit by a flying four-foot saw blade in Eugene over the weekend. A construction crew was using the blade on a piece of equipment when it flew off at high speed, raced across a parking lot and slammed into the wall of a convenience store. Surveillance video showed a customer going through the door seconds before impact. The blade was embedded halfway into the wall next to the door. No one was hurt.
