Firefighters from the 158th Fighter Wing, Vermont Air National Guard and the South Burlington Fire Department, climb the stairs of a six story parking garage tower to mark the highest point firefighters reached in the twin towers on 9/11, Burlington International Airport, South Burlington, Vt., Sept. 11, 2019. While carrying the U.S. and Vermont state flags, they ascended to the top and back down 18 times, the equivalent of the 78th floor of the south tower that firefighters reached during the attacks which took the lives of 343 firefighters among the 2,977 total victims.
