I think cutting off access between the cockpit and the passenger cabins is a good idea. Also we should perhaps return to having armed Sky Marshals on flights.
Then, of course, we should start killing known terrorists and their sponsors without waiting to pin a specific incident on them. We should also try non-citizen accomplices captured in this country before military tribunals, not in civilian courts.
No "24-48-96 Hour Notice to give up Bin Laden" garbage--Afghani's are harboring anti-US terrorists--
Shore up our borders--Stop letting in foreigners from these enemy nations

Agreed!
Then you're going to have to redesign the planes to include separate bathroom facilities for the cockpit crew. And the ability to prepare their own meals, instead of having them delivered by the "steward/esse/s".
I don't think the flight crews are going to go for it, terrorists or not. It would be easier to train the cockpit crews to be heartless SOBs that will sacrifice the lives of the rest of the crew and passengers on board before putting flying bombs in the hands of whatever terrorists might be on board.
