Getafe Airfield was the site of the world’s first successful rotorcraft flight, on January 17, 1923. Lieutenant Alejandro Gómez Spencer piloted a C.4 Autogiro designed and built by Juan de la Cierva, who tested a series of autogiros between 1920 and 1924 at the Getafe site. Cierva’s autogiros introduced important technologies and flight techniques that led to the development of helicopters and other rotary wing aircraft.

 

In 1902 and 1903 he requested some patents for the system. With the Telekine, Torres-Quevedo laid down modern wireless remote-control operation principles. Torres Quevedo also made some important contributions to aeronautics, a field in which he carried out important research on dirigible balloons.

For 2,000 years, Aqueducto de Segovia has been conveying drinking water from the Frio River to Segovia, approximately 18 kilometers away. Built under the reign of Roman emperor Trajan, the aqueduct is one of the most intact and best-preserved Roman engineering masterpieces. Roman engineers built the channel of the aqueduct with an average one percent gradient over its whole length.
