The Antonov An-26 (NATO reporting name: Curl) is a twin-engined turboprop civilian and military transport aircraft, designed and produced in the Soviet Union from 1969 to 1986. The Antonov An-26 was the standard short-range Soviet tactical transport during the latter half of the Cold War. Developed from the previous An-24 design, it was first Soviet military transport aircraft to have a fully pressurised cargo hold. Production ended in 1986 after about 1410 An-26s had been built, most of them for military operators. The An-26T is the unofficial East German designation for An-26s operated by Transportfliegerstaffel 24 (24th Transport Squadron) at Dresden-Klotzsche.

The Technik Museum Speyer (Speyer Museum of Technology) is a technology museum in Speyer (south-west of Heidelberg), Germany. The collection includes: aircraft, classic vintage cars, racing- and classic motorcycles, historic fire engines, ships, massive steam locomotives, mechanical instruments, rarities and fashions. A special part of the collection is the Russian Space Shuttle Buran. The collection is displayed both indoors and outdoors, and finally there is an IMAX theater. The museum was established in 1991. It is closely associated with the Technik Museum Sinsheim (Sinsheim Museum of Technology). The latter suffered from a lack of space and a second location was opened in Speyer.
