I have the fortune and pleasure to fly in it in 1953, in the Military Pilots School (El Copero- Sevilla - Spain). It was (65 years ago) a great plane.

Designed as advanced trainer after the civil war, this airraft was the typical example of the very limited possibilities of the spanish industry in the forties. The fixed landing gear was the same used in the duch Fokker XXI fighter, a design that was acquired by Spain but never took form due the war. The chosen engine was an italian Piaggio first,but it did not succed and then a british "Cheetah" was used when this british were available in Spain. The plane was not popular among the pilots cause it was prone to stall at low speeds and this caused many accidents. Definitevely the HS42 was not a trainer. It was substitued by the Beech Mentor in the early fifties.
