11/30/2009. Remarks by Johan Visschedijk: "In 1975, 17 of a 24-plane fleet of Bonanza, Baron and King Air aircraft were grouped before delivery to the Spanish Subsecretaría de Aviación Civil del Ministerio del Aire (Undersecretary's office of Civil Aviation of the Air Ministry). They were operated by the ENA (Escuela Nacional de Aeronáutica, National School of Aeronautics). Between 1972 and February 1976, the Spanish Air Ministry accepted 85 Beech aircraft: 54 Bonanzas, 19 Barons, and 12 King Airs.
