It's being used to create hyper-detailed maps of the WTC disaster site from an altitude of 5000 feet to detect shifts in the rubble as well as areas in danger of collapse."

    there is nothing "nifty" about 6,700 innocent Americans dying in the most horrible way possible at the hands of a few highly irrational people

    Some of those people were Canadian, quite a few of them were other nationalities as well.

    I personally don't need a flag to bring me together with other people ; I feel horrible for those people who died, and their families - but more importantly, I refuse to think of them as Americans. They were people. Like you and me.

    If I die in a tragedy similiar to that, I would hope the people who witness it don't assume I am of their nationality, believe in their religion, or that I would necessarily condone what they do to avenge my death.

    Not everyone who doesn't think like you doesn't believe what you believe ; they just believe it differently. And I believe in Freedom, the type of Freedom you don't get from Killing people, Wearing a Flag, or necessarily by calling yourself a member of a larger group.

    We're all feeling a lot of anger after this tragedy, let's just admit that and stop with the paranoia regarding people who "Live amongst us". When we seperate ourselves from "Them", we fight the notion that some people don't agree with status quo. That some people don't believe in our Government, or all of Our Laws. It is that diversity that gives us our freedom. It is MURDER, that takes our freedoms away.

    So while Murderers live amongst us (as has always been the case) ; those who don't believe everything we believe as a whole are good for the economy, for our diversity, and for our way of life; they represent our Acknowledgement of Freedom and our Acknowledgement that we personally do not see eye to eye with everyone else in our country.

    The greatest risk to our freedom as a whole is accepting that we have freedom as a whole.
