The Do 25 first prototype took its maiden flight from Tablada, near my home, 70 years ago today. Designed by Claus Dornier‘s Spanish OTEDO (Oficinas Técnicas Dornier) and built by CASA at Cádiz and Sevilla, it was powered by a meagre 150hp ENMASA Tigre which didn’t allow the design to reach its full potential. The modified second (P2c) prototype and its Continental O-470-J engine began to correct that shortcoming. The Loser.
The somehow clumsy-looking Do 25 P1, wearing the Spanish military registration XL.9-1, while assigned to the Escuadrón de Experimentación en Vuelo, Torrejón de Ardoz (Madrid). Photo taken during the “great aerial fest” which took place at El Prat airport (Barcelona), 1956. Notice the chaos of oil drums and the P1’s tiny underwing fuel drop tanks later discarded in the Do 27.
