9/11 is a tragedy that will continue to shape our lives. This footage was shot from our East Village office window, and is in memory, not only of all the people who lost their lives in the World Trade Towers, but to all the people who are still losing their lives because of this attack. The footage taken was instrumental in the government's investigation of the Twin Towers' collapse, and was used in the official public report (on page 10 of the pdf) that NIST presented in New York.
