In addition to the advantageous geographic situation, an Opel factory was opened in 1982 inFigueruelas, a small village nearby. The progressive decline of the agrarian economy turned Opel into one of the main pillars of the regional economy, along with Balay, which manufactures household appliances; CAF (Construcciones y Auxiliar de Ferrocarriles S.A.), which builds railway engines for both the national and international markets; SAICA and Torraspapel in the stationery sector; and various other local companies, such as Pikolin, Lacasa and Imaginarium SA.
The city's economy benefited from projects like the Expo 2008 (the official World's Fair, with the theme of water and sustainable development, held between 14 June and 14 September 2008), Plataforma Logística de Zaragoza (PLAZA), Parque Tecnológico de Reciclado (PTR), as well as being on the route of the AVE high-speed rail route since December 2003, which consolidates the city role as a communications hub. Currently, Zaragoza's Airport is a major cargo hub in the Iberian Peninsula, only behind Madrid, Barcelona and Lisbon.
Zaragoza is home to a Spanish Air Force base, which was (until 1994) shared with the U.S. Air Force. In English, the base was known as Zaragoza Air Base. The Spanish Air Force maintained an F/A-18 Hornet wing at the base. No American flying wings (with the exception of a few KC-135) were permanently based there, but it served as a training base for American fighter squadrons across Europe. It is also the main headquarters for the Spanish Land Army, hosting the Academia General Militar, a number of brigades at San Gregorio, and other garrisons
