It is still a source of considerable irritation that I cant take my wife and children in the cockpit but that cabin crew of uncertain pedigree and orientations can join the airline from north Africa or the Middle east and after a couple of short weeks training have unrestricted access.
I still consider this to be the greatest threat to cockpit security. The sept 11th hijackers were probably overtrained for the job of guiding an aircraft at a large target. A few hours on a flight sim would be sufficient.
The company (chief pilot ?) should be able to issue cockpit passes for long term crews spouses and children.
It has been pointed out a few times in this thread already that many a lad was inspired into a flying career after a cockpit visit. I was that lad and I don’t regret a minute of it.
