What would you do in this inflight situation?

a hijacking can happen again, unlike the other person before me said it cant happen.i flown several time overseas since 9/11 and and i watch people very closely in airport and i watch the tsa also. they do their job half hearted. as for me, i would do all i could do in a bad situation on a plane if we got hijacked. i will gladly die to save many people, just like the plane that crashed in pa.
