FDNY: Small Fire out Quickly at World Trade Center Firefighters responded to the 89th floor of One World Trade Center to help construction workers put out a small fire in some wooden decking. The New York City Fire Department says it got the call for help at 7:15 a.m. Saturday. Workers at the unfinished tower extinguished most of the burning wood themselves, but firefighters were still on the scene wetting down the area an hour later. The skyscraper is already over 1,200 feet high, with a few hundred feet more to go until it reaches its full height.
