We may find some day that we can no longer carry bags of any sort into the restroom on flights.
While some could argue that they need a shaving kit, aren't razors prohibited items these days?
I'm sure that I might have been bothered by a large group of passengers who moved about the plane a lot (if nothing else, it makes stewardess service difficult and can lead to a lot of bumping people in the aisle seats).
Reading this article, I see nothing especially unusual about the incident (apart from raising the suspicions of passengers and the air crew). If the man in the yellow shirt was the tour leader (if not band leader), they may have felt obligated to talk to him about their plans for their final destination.
Passing notes can be serious or nothing.
For what it is worth, James Woods reported seeing a dry run for the 9/11/2001 flights.
nothing unusual seven men not strapped in for the appropach after the announcement has been made, landing is eminent and all are in their seats. I travel alot on planes, at least 20 trips a year, and this doesn't happen. One straggler may do a pit stop but this is highly unusual, highly.
