Interesting idea: Stand UP and step into the aisles. This forces the bad guys to climb over seats etc to get to the cockpit and they could be tangled up even there, fairly easily. Of course if there's an air marshal on board, standing up might get you a bullet in the head. Don't bet the marshal will hold his fire, either. I'll bet they'd be happy with a few passenger fatalities versus the whole aircraft shot down by an F-15.

Judicial meanz, this is your area of expertise, what do you think?

Personally, I would not do anything to impede the Air Marshalls if they rose and identified themselves to take action.

If there is a firefight getting ready to happen, you can position yourself in the crossfire and cause the bad guys to get the advantage.

I would wait until the Air Marshalls took action, and then help them out if they need reinforcement, assistance, or whatever else they request.

Also helps you defend yourself from the inevitable lawsuit filed by terrorist sympathizers later on.
