Thanks for that link Trakball.
It's still a grey area about the reasons for using video cameras or not. As I said previously, I have watched many videos on youtube taken from the flightdeck, which by their nature, must have the full approval of the airlines concerned.
Whether the videos taken from the passenger cabin were allowed or not is difficult to say, but surely if it is allowable on the flightdeck there appears to be no sound reason to impose a ban on use by passengers.
