Thanks for your input but I have to disagree.
With the technology available today I believe that you could install as many cameras and monitors as were deemed necessary on a large passenger aircraft without weight becoming a critical factor.
The whole caboodle would likely be less than the weight of a single passenger.
I also remember the days when the Captain used to walk through the aircraft, and a very reassuring thing it was too.
I think we have all become far too paranoid since 9/11, and I would welcome a return to the days when flying was much more of a pleasure than a chore.
