BRITISH PROTOTYPE AIRCRAFT RAY STURTIVANT PRC 1995 27 x 22 cm. 216 pp. HB/DJ Every advance in aviation has been the result of a problem encountered and then solved. From the earliest days Britain was in the forefront of progress, and by 1917 it was the practice to build special aircraft for trials purposes to test some theory without necessarily any intention of placing those machines in production. This arrangement was formalized by the issuing of Government contracts to an Air Ministry specification. The aircraft designs encompassed within this system embrace the more important aspects of British aeronautical progress, and this book charts the history of such developments.
