Good Job
You did a good job telling me a story without using words. The images where clear and I could tell what you were trying to say. Very well done in that department.
However, your choice of music was really jarring to me. It just did not fit for me. Take that with a grain of salt because music is subjective. Others might have liked it.
9/11 has become like Pearl Harbor, all sorts of consiracy theories about... if we knew the Japanese where coming because we cracked their codes and had our important ships all out to see (the carriers) why didn't we warn the sailors and at least cut down on the loss of life? Conspiracy theory yes, and can never be proven, but even to this day people are still trying to figure out this kind of stuff.
