Airlines could provide larger, more spacious seats, with more leg room and wider aisles, and they could let the passengers smoke again. Airlines can, and are beginning to, limit the amount of alcohol that passengers drink on board, and to refuse admittance onto an aircraft if they turn up at the gate drunk. This may seem extreme, but the problems seen in flight are similar to the problems seen in city centres all over the world on a Friday night. Only in these instances, the problems occur at 35,000 feet, in congested airspace, and could have a life threatening effect on 200 - 300 other passengers. Unlike the Friday night reveller, the air rage assailant can not be thrown out of the door.
Surveillance cameras have been extremely effective in as a deterrent to crime. If airline passengers are made aware that the cabins are fitted with cameras that will record the whole flight, they will be less likely to become disruptive. The FlightVu internal cameras not only deter criminals, if an incident did occur in-flight the indelibly stamped recorded images (registering the time, date and location) would be admissible as evidence in court. This would aid and speed up prosecution of the offender.
