One of two DC-3s on display at the parachute jumping base of the Escuela de Fuerzas Especiales No.9 (hence the "EFE-9" on the fin), along the Pan-American highway north of Latacunga. A photo of the other one can be found here. Neither aircraft could be positively identified because all data plates had been removed, but this one is suggested to be FAE4341, ex PP-ANP. This may have undergone a conversion during its civil years in Brazil in the 1950s, explaining the pax door. (Nikon D610 + Nikkor 18-35mm f/3.5-4.5G ED AF-S).
