I think your idea about maneuvering the aircraft to stop the sucker/s is a good one.
I suggest also that, knowing the threat on board, one pilot should take care only to fly the plane and the other should use any available mean to protect the other. "You fly, I fight" as an american Captain said.
We should be armed as well, a small caliber (.22!) shouldn't be to dangerous for the stucture.
We should have a self-defense training.
We should fly with a flying suit instead of our nice but very unconfortable uniform, especially the tie (very dangerous if grabbed).
At the moment I fly with a pepper spray with me, but is it going to be useful in case I need it?
Bottom line: we need safety on board, we have to restore safety with any mean, we have to be trained to use the "mean" (otherwise we can be more dangerous than the hijacker!!!)
Happy landings!
