It was on this day in aviation history that the Antonov An-24 took to the skies over the Soviet Union.
The Antonov An-24 was created on the drawing boards at Antonov Design Bureau in the mid to late 50s of the previous century. Initial production was by the Kyivm, Irkutsk, and Ulan-Ude Aviation Factories.
The aircraft was designed as a replacement for the piston-powered Ilyushin Il-14 Aircraft for transport up to medium-length routes. A design consideration was the suitability of the aircraft to operate van unprepared rough runways in the remote regions of the Soviet Union. this resulted in a robust design with a high mounted wing which gives good clearance of the props and engine inlet. The aircraft has an impressive power-to-weight ratio. The design was such that the aircraft needs hardly any ground equipment.

The qualities of the aircraft led to an impressive list of subvariants, a total of 27 different variants have been designed since the first flight, some examples;
An-24 (4 built) Prototypes
An-24A First production version
An-24B The second production version, with an additional cabin window on each side of the fuselage
An-24T Tactical transport version
An-24V-II An export version of the An24, deliverable in different configurations - 50 seat passenger - Combi passenger / cargo - Full freighter version
Besides the different versions of the An-24 being developed it also served as the basis for the development of other aircraft.
An-26 Tactical transport aircraft
An-30 Photo-mapping and survey aircraft
An-32 Tactical transport aircraft
An-50 1960's project to power the aircraft with 4 jets
The aircraft would be built at 3 different factories, with a total of 1285 airframes being built when the production in the Soviet Union was shut down in 1978.

A variant is still being built in China by the Xi'an Aircraft Industrial Corporation, the reverse-engineered the An-24 and market the aircraft as the Xian Y-7, which has now been upgraded with western engines and avionics and is now marketed as the MA60
