I call BS on this claim. There is no mention of it on the WCVB site, and you can be sure that this would have been splashed all over if it were true.
This a like a classic urban legend, with references to reputable sources (WCVB). The camera shots look amateurish, not done by a professional.
Oh, so a news organization does not put this on their site - but in phone calls confirms it is their video and their cameraman - then it is not true?
Are you from the Planet Kolob?
