At last, on July 27th , Sparey has plans for a "new" model, unusually graceful and well-proportioned. This is because it is based on a German rocket model of 1936 [Ed.: This is undoubtedly the Haase Rocket Plane, depicted by Frank Zaic in his Model Aeronautical Yearbook of 1944]. In discussing the model Sparey doesn't make it clear whether he is talking about the German model or his own, or when the flights of the latter happened, if at all. He mentions liability to damage and the erratic behaviour of the rockets but this could be about the German original. It is clear that our author was interested in rocket flights at that time and gathered information on rocket fuel but whether he built and flew such models is doubtful.
