A video has surfaced of a Leominster man “out of control” on a United Airlines flight from L.A. to Boston. According to fellow passengers, the 33 year-old man started rambling saying his father was Dracula and that he was going to kill people on the flight. The man tried to open an emergency exit door and stabbed a flight attendant with a jagged spoon. With today’s airport security how did this happen? If you were a fellow passenger on this flight, would you have intervened?
