PHOTOS: At 9:37 am Eastern Time on September 11, 2001, two fire captains—Michael Defina and John Durrer—from the Metropolitan Washington Airports Authority Fire & Rescue Department, based at Ronald Reagan Washington National Airport, were standing on the departures level of the main terminal. They were responding to a minor vehicle accident, but their attention quickly turned toward a low rumble, followed by smoke rising to the northwest. Already alarmed by the reports of two airliners impacting the World Trade Center towers in New York City, both sprang into action. Defina jumped into his chief’s wagon, while Durrer and three others jumped into Engine 335, a conventional pumper with rescue equipment.
