On 7 June 1938, sargento Francisco Sánchez Matos of the Escuela de Vuelo Nocturno at El Carmolí scrambled in Koolhoven FK.51 ‘EK-008’ at 00:30, but he was forced to crash-land when his engine seized due to oil starvation. The FK.51 turned over in front of the base hospital and Sánchez Matos was wounded and the aircraft destroyed.
