The shots from 6:02 to 6:20 appear to be of the National 9/11 Flag, which has a very inspiring story behind it. The flag was recovered from a building near the Twin Towers and left in storage for 7 years. The restoration effort began in 2008 with residents of Greensburg, Kansas, a town destroyed by a massive tornado the previous year, using pieces of their tornado-damaged flags to patch the original. The flag then toured all 50 states with patches and stitches being added at sites of national significance (e.g. Mount Rushmore) or in communities affected by disasters of their own. A partial list of places that the flag has visited is at this link:
The flag is connected with a wonderful volunteer group called New York Says Thank You, which helps disaster victims all over the country in gratitude for their support of New Yorkers after 9/11. They came to my hometown of Utica, Illinois, after a deadly tornado in 2004 and their help was much appreciated.
