Morticians at Dover Air Force Base, Delaware, find a secret note inside the stomach of one of the Flight 77 passengers who died in the Pentagon attack, which the passenger wrote and then ate shortly before they died, but the morticians will later refuse to reveal what the note says. [Washington Post, 3/4/2018; CBS News, 3/5/2018] The incident will only come to light around 2015, when bestselling thriller writer Brad Meltzer is conducting research for his novel The Escape Artist, which will be released in 2018.
Writer Will Learn about the Note during Research for a Novel – For his research, Meltzer will visit the Dover Port Mortuary at Dover Air Force Base, where the remains of the victims of the Pentagon attack were sent for identification (see September 11-November 16, 2001). [CBS Miami, 3/5/2018; New York Times, 3/16/2018] There, he will discuss the plot of his forthcoming novel with a mortician. He will ask if there is any way a person could leave a hidden message inside their body before they died. The mortician will answer that “if you’re on a plane that’s going down, if you handwrite a note and eat it, the human stomach has enough liquids to protect the note from burning” in the fire that erupts when the plane crashes, Meltzer will later recall. The mortician will then tell Meltzer that this “really happened” on 9/11.
Writer Will Be Told How the Secret Note Was Found – He will say that after the remains of the victims of the Pentagon attack were brought to Dover Port Mortuary, “When the morticians worked on one of the bodies, they found a note inside.” Apparently, according to the mortician, “as the plane was going down, one of the victims on Flight 77 actually ate a note, which was found by a Dover mortician.” He will call the passenger’s note the “ultimate message in a bottle.” He will refuse to tell Meltzer what it said, though. Meltzer will assume that the note must have been written by someone in the military, since, he will comment, “Who else would know that the liquid in your belly could preserve a piece of paper?” [Washington Post, 3/4/2018]
Pentagon Attack Victims’ Remains Are Identified at Dover Air Base – The remains of the victims of the Pentagon attack are flown to Dover Air Force Base after 9/11, with the first set arriving there on the afternoon of September 13, and mortuary operations are fully underway by that evening. Over the next 16 days, a team of forensic specialists, scientists, and support personnel from the Armed Forces Institute of Pathology works at the Dover Port Mortuary to identify the victims. The FBI has a liaison at the mortuary while the remains are being identified, in case evidence is uncovered during the identification process. [Pentagram, 11/30/2001; Rossow, 2003, pp. 95; Condon-Rall, 2011, pp. 75] The secret note is presumably passed on to this liaison after being recovered from the victim’s stomach.
