i was recently thinking about this... i miss the good old days before 911.... i remember once i got to sit in the cockpit of a BA747 when i was like 15...the view is increadible....i hope one day some airline comes up with some kind of video intercom so that enthusiasts can talk to the pilots and whatnot... instead of taking kids to the cockpit they can sit em down at the video terminal and have a psudo visit with the flight crew...
its still secure and the doors can remain locked...
