CCTV footage shows a woman falling head first onto the tracks at the Back Bay subway station in Boston. At the time of the fall, 44-year-old Kelly Smith, was reported to be suffering from pain on the right side of her body. The incident, which was captured by station security cameras, shows the woman walking down the steps and into the station before she suddenly veers to her right, steps over the edge, and crashes onto the tracks face first. Several bystanders rush to the woman's assistance and help her back onto the station platform. A spokesperson for the Boston Transit Agency said luckily, the woman didn't make contact with the third rail. There was no train in the immediate area, either.
