The "Museo del Aire" (Aviation Museum) at Cuatros Vientos airfield in Madrid houses an impressive (mainly military) collection of aircraft. This airfield was Spain’s first military airfield and opened as long ago as 1911. Over 100 aircraft (fixed wing, rotary wing, gliders and structural components) are currently on display, however the impressive collection also comprises photos and paintings, squadron badges, engines, airfield equipment, weapons, and other memorabilia.
Famous aircraft on show include the Dragon Rapide, which flew General Franco from the Canary Islands to Tetouan kicking off the Spanish Civil War in 1936 and the Heinkel He.111E-1 "Pedro". Assigned to the Conder Legion in Spain in 1937, this German aircraft was so fast it could operate without fighter escort. This particular aircraft is the oldest surviving example.
