This is all 20/20 hindsight now. I am in favor of some self-definese traing for the flight crew (kung fu?) including the FAs. They have had to deal with air rage, now hijackers who took control with only knives and cardboard cutters.

I also think the pilots need a monitor to see what's happening in the cabin. It can give the pilots warning and perhaps some precious minutes to do whatever he needs to do.
