BlueEagle,
Your probably right, I might die in the attempt. However, the rules have changed. Anyone who finds themselves facing a terrorist on an aircraft had better face up to the fact that they are dead anyway. What good is an anti-terrorist squad of SAS or SEAL's when the jets are being used as missiles.
If you are going to die you might as well go as the United Airlines flight did. By doing what they did and sacrificing their lifes, I have no doubt that they saved hundreds of others. God bless them.
Sitting in my seat hoping that everything turns out alright is no longer an option. We have to take control over our own destiny.
Even if aircrew do have a weapon, the training you are talking about takes a very long time to get proficient. Most likely the result would be someone shooting themselves in the foot.
