Farnborough International Air Show 1978. A three engine turboprop DC-3 conversion. Only two were built and this aircraft spent a lot of time in the Arctic and Antarctic. Built as a C-53 for the USAAF as 41-20133 and taken on charge on 30 Mar 1942. To TWA as NC44783 on 30 May 1945. Later to N44783, N2001, N700CC and N4700C. Converted by Conroy to a DC-3TP turboprop on 13 May 1969. To N23SA in May 77 and converted to a Tri-Turbo 3. To Polair on 20 Aug 1979. Noted derelict opposite the Basler facility during EAA2023 at Oshkosh on 26 Jul 2023.

Delivered to the USAAF as C-53 41-20133 in 1942. To TWA as NC44783 in 1945. Sold as N2001 in 1950, then to N700CC in 1962, N4700C in 1967 and N23SA in 1977. Converted to a Conroy Tri-Turbo Three. To Basler Turbo Conversions at Oshkosh, WI in 1994 and used for parts. Remains still there in 2010. The fictitious coastguard-like "Maritime Patrol And Rescue" markings are for promotional sales purposes only.

Never (ski-)jump to conclusions. The Conroy Tri Turbo Three was not using the Harrier ski-jump rig at the 1978 Farnborough Airshow. Jack Conroy's company had also converted the CL-44-O Skymonster, and he had worked for Aero Spacelines converting the Stratocruiser-based Guppy series in the 1960s. The coastguard-like "Maritime Patrol And Rescue" markings are bogus and for promotional sales purposes only.
