"The people on Flight 93 died for the country, didn't they? "
that's a foolish statement. No, they did not. They had no idea that what they were involved in would be one of the worst days in our modern history. They didn't know they were only 1 of 4 planes hijacked in a plot to take out America's most important institutions. All they knew was that they were hijacked by terrorists and they needed to fight for their own survival. Not america's. Thier own.
I don't see how they died for their country by unfortunately being in the wrong place at the wrong time. Yes, that sounds very crass, but that's what it is.
To die for one's country, to me, means some sort of sacrifice. You willingly give your life to protect something you believe in. Those people did not willingly give their life, they fought back, in an attempt to save their own lives and see their loved ones again. They did not sacrifice thier lives for us.
