HISPANO BUCHÓN TECHNICAL DETAILS: Key differences under the skin between the HA-1112-M1L and its forerunners

The Merlin 500/45 installation is depicted well in this view of a Buchón being run up on the apron at Duxford in 1968.

The Buchón’s fuselage consists of front and rear sections, riveted together. Manufactured in Duralumin with a skin thickness of 1.2mm, the cockpit section is flat-sided and attached by countersunk rivets for a flush finish. In service, EdA pilots placed great faith in its construction as it generally stood up well in accidents. The canopy is very heavy and opens to the right. It is jettisonable, as is the rear fixed section which is released via two springs.
