CASA C-207 Azor
The CASA C-207 Azor was a transport aircraft produced by Construcciones Aeronáuticas SA (CASA). It was a scaled-up version of the CASA C-202 Halcón and was designed for the domestic civil market. The C-207 received no civil orders, but the Spanish Air Force ordered ten. The first model, designated T.7A entered service in 1960. Ten more aircraft were ordered and configured for paratroop or cargo transport, designated CASA 207C(T.7B). The CASA 207 was one of the first aircraft to be designed by CASA in order to replace the transports in current service at the time, like  the CASA 2.111 (Heinkel He 111) and the CASA 352 (Junkers Ju 52). The two prototypes and 20 production aircraft served in the military until the early 1980s. Additionally, most of the aircraft were delivered to the 35th Transport wing. Development. The CASA 207 was developed as an airline-suited aircraft, for the short- to mid-range routes that were common in Spain and Europe. The Azor was deemed to be obsolete and uneconomical for its time and standards, for which better aircraft were available for its role. So, CASA turned its marketing attention to the Spanish Air Force, which  had interest in a "modern" transport aircraft. CASA Had previously experimented with transport aircraft to replace types already in service, such as the CASA C-201 and CASA C-202. They were plagued with underpowered engines and were cancelled. CASA decided to make a version of the 207 for the Spanish Air Force that would follow up to the C-201 and 202. The CASA 207A was built for the Air Force with a capacity of 40 passengers plus a crew of four. A batch of ten C-207C (or T.7B) were built with large doors and capacity for 37 Paratroopers. The Hamburger Flugzeugbau  and CASA offered a version driven by Turbopropeller engines, but this plan was dropped due to the availability of the CASA 212 Aviocar. Survivors. Out of the 22 built, five are known to have escaped the scrapping that the other C-207 aircraft were subjected to upon their retirement. Of those, two are at the Spanish Air Force museum, one is at Getafe Air Base, one is preserved in the exterior in Sevilla after a 2015 restoration, and one is a derelict, ex-fire trainer at Seville, albeit a fuselage.
