Originally a C-131E and allocated USAF serial 57-2548, but not delivered and went to the FAA as N101 then N91 as an airways calibration aircraft. Became N6226M in 1996 then cancelled as destroyed in 1997. (According to the Joe Baugher website, this and its sister ships were not legally considered as Convair products, but actually certified by Allison Prop Jet Conversions and Pacific Airmotive. This explains why they were not usable commercially after retirement and any civil registrations were for ferry purposes as for this one and for c/n 478 which used C-FJVD.)

About to land on runway 33 at DCA. This shot was taken from my canoe anchored just offshore in the Potomac.
