A Pennsylvania woman is lucky to be alive after a freak accident at a McDonald's drive-thru.

Police say Janet Pfeifer was at the drive-thru window when she somehow dropped her bag of food. When the 76 year-old went to pick up the bag she fell out of her car. Then, the situation went from bad to worse when Pfeifer's car rolled forward and ran over her.

The incident happened at the McDonald's near Unity Township, PA.

WHAM reports that when the vehicle had rolled forward it hit a block wall and hen rolled backward over the woman.

Pfiefer was taken by ambulance to a nearby airport and then flown to UPMC Presbyterian hospital in Pittsburgh.

She was listed in serious condition Tuesday morning.
