Human remains from the Flight 93 crash site are moved to a temporary morgue that has been set up at the Pennsylvania National Guard Armory, several miles away in Friedens. High-tech mortuary equipment has been brought to the armory in a tractor-trailer. [Pennsylvania Emergency Management Agency, 9/12/2001 ; WTAE-TV, 9/13/2001] 75 to 100 specialists, including pathologists and fingerprint experts, are involved in the attempt to identify the remains. Forensic anthropologist Dennis Dirkmaat says that because the remains have suffered “extreme fragmentation,” most will need to be identified using DNA analysis. [Washington Post, 9/14/2001] When remains cannot be identified at the temporary morgue, samples are sent on to the Armed Forces DNA Identification Laboratory in Rockville, Maryland, where samples from the Pentagon crash are also being analyzed (see September 11-November 16, 2001). [Pittsburgh Post-Gazette, 9/25/2001; Stars and Stripes, 10/8/2001; KCRA, 12/20/2001] By December 19, the remains of all 40 passengers and crew from Flight 93 have been identified, using fingerprints, dental records, and DNA. Investigators have, by a process of elimination, also been able to isolate genetic profiles of the four hijackers. [Pittsburgh Post-Gazette, 12/30/2001; DMORT National News, 1/2002; Associated Press, 2/26/2002; Stripe, 9/20/2002] Searchers recovered about 510 pounds of human remains at the crash scene, equaling about eight percent of the total bodyweight on the plane. According to Somerset County Coroner Wallace Miller, everything else was vaporized. [Washington Post, 5/12/2002; Age (Melbourne), 9/9/2002; Canadian Press, 3/28/2004]
A report suggests the crash site of Flight 93 is being searched and recorded in 60 square-foot grids. [News Journal (Wilmington, DE), 9/16/2001] This approach is preferred by Wallace Miller, the local coroner, and Dennis Dirkmaat, a forensic anthropologist involved in searching the crash site. According to journalist and author Jere Longman, “The distribution patterns developed from such precise marking of airplane parts, remains and personal effects might have told them such things as exactly how the airplane struck the ground. Theoretically, by associating the location of particular remains with the location of parts of the airplane, they may have also gained some clues about which passengers had rushed the cockpit.” However, almost a year later Longman reports that this approach was not followed: “The FBI overruled them, instead dividing the site into five large sectors. It would be too time-consuming to mark tight grids, and would serve no real investigative purpose, the bureau decided. There was no mystery to solve about the crash. Everybody knew what happened to the plane.” [Longman, 2002, pp. 262] While the FBI claims there is no mystery, some news articles suggest the plane was shot down. (For example, [Philadelphia Daily News, 11/15/2001; Independent, 8/13/2002] ) In addition, at the time of this decision, investigators are still considering the possibility that a bomb might have destroyed the plane (see September 14, 2001). Unlike every other major airplane crash in modern history, no National Transportation Safety Board (NTSB) investigation is being conducted into the crash of Flight 93 (see After September 11, 2001).
