Van Harp, the head of the FBI’s Washington, DC, field office, is away from the capital in South Carolina for his summer vacation, and has to be flown back to Washington in an FBI plane to help respond to the terrorist attacks. [Washington Post, 3/4/2002; US Department of Health and Human Services, 7/2002, pp. C45, C47 ; 9/11 Commission, 12/15/2003 ] Harp took command of the Washington field office (WFO) as its new assistant director in charge in July this year. [Washington Post, 4/18/2003; Federal Bureau of Investigation, 2010] But on this day he is in Hilton Head, South Carolina, on vacation with his wife, children, and grandchildren. He learned of the first plane hitting the World Trade Center when his secretary, Donna Cummings, paged him shortly after the attack occurred. Harp then called Cummings and she told him what had happened. He switched on the television in time to see the second plane crashing into the WTC, and had known then that he needed to return to Washington.
FBI Granted Permission to Send Plane to Collect Harp – Because all planes have been grounded across the US (see (9:45 a.m.) September 11, 2001), the FBI initially arranged for state troopers in South Carolina, North Carolina, and Virginia to drive Harp back to Washington. But the bureau was then able to get special permission from the FAA to send an aircraft to fly Harp home. [Kessler, 2002, pp. 424; Washington Post, 3/4/2002; US Department of Health and Human Services, 7/2002, pp. C47 ] The FBI therefore sent one of its aircraft to collect Harp from Hilton Head Airport. The small, single-engine plane received clearance to take off from Manassas Regional Airport, 30 miles west of Washington, at around 2:30 p.m. The time when it lands in Hilton Head is unstated, as is the time when it lands back at the Manassas airport. From the Manassas airport, Harp drives to an FBI command post at Washington Dulles International Airport and then arrives at the WFO sometime later in the afternoon. He will stay at the field office until 2:20 a.m. [Federal Aviation Administration, 9/11/2001; Kessler, 2002, pp. 424; Federal Aviation Administration, 3/21/2002, pp. G-2, S-41]
Three of Office’s Four Leaders Absent – The WFO is the second largest of the FBI’s 56 field offices in terms of staffing. It comprises 657 agents and 650 professional support staff. Serving under Harp, three special agents in charge (SACs) direct the office’s administrative and technical, criminal investigations, and national security divisions. However, of the WFO’s four senior leaders, only SAC Arthur Eberhart, the head of the administrative and technical division, was present at the office when the terrorist attacks took place. SAC Ellen Knowlton, who headed the criminal investigative division, was recently reassigned to FBI headquarters, and so her position is currently vacant. SAC Timothy Bereznay was only recently appointed to head the national security division, and so he has not yet reported to the WFO. [US Department of Health and Human Services, 7/2002, pp. C3, C45 ; 9/11 Commission, 12/15/2003 ; Federal Bureau of Investigation, 4/6/2006] The WFO will be one of the key FBI offices involved in the fight against terrorism following the 9/11 attacks.
