Commemorating the creation of the El Bosque-based Military Aeronautics School and their first military flight in early 1913, Chile’s Air Force celebrated 100 years of military aviation in the first week of March 2013. Summarizing a century of aviation progress in words and facts, the centennial was marked by a formal ceremony held at El Bosque, an open day held at Pudahuel and a host of other social and cultural events elsewhere. The main activities were covered by Gaceta Aeronáutica correspondents on-site and a complete debriefing is presented inside.
