Jetpilot,
I appreciate your well-reasoned response, and also respect the limitations on what you can/can't say.
Balancing what you posted with how it feels to be one of the sheep in coach, I still cannot say what I would have done in the situation described in the article.
Personally, 9-11 hammered home the message that being proactive, rather than wait-and-see, could be the difference between a minor incident and a major catastrophy. However, if there were truly an incident underway, it would be a horrible mistake to interfere with the crew's ability to handle it.
So it seems to me, the key is whether or not the situation is under control. I gather from your post that if it were not, it would be obvious. From the article, I think I can make the case that it may - or may not - have been. The simple fact that the flight attendants were freely moving about the cabin and able to talk to passengers should be comforting. However, I cannot understand ANY reason why the level of activity she described by middle-eastern looking men, carrying bags in and out of the lavatories should be allowed. Worst of all, the man in sunglasses who was hovering near the door of the cockpit was apparently never asked to take his seat. Observing this, I would have to wonder if the plane were already "taken" and the attendants were under duress to appear "normal".
I would not advocate tackling middle-eastern looking guys in the isles just because too many of them are standing up. But I think it would have been an interesting test for someone to go stand next to the sunglasses guy by the cockpit. Just stand there. Nothing more. If he had a legitimate reason to be there, (Air Marshall?) then I would be asked to sit down and nothing more. If not, we would both be asked to sit down or not congregate by the door. I bet based on his reaction, I'd know if he belonged there or not.
I suppose if the pilots had any reason to not like the activity going on, they could have easily turned on the seatbelt sign, asked everyone to be seated immediately, and simulated a little turbulence with the joystick...
