  1. 'The future thread of Luftwaffe', around min 3:39 in this video means, Roy Fedden cited becoming aware that 'War was unavoidable', that UK had plans to attack Germany; they declared war when Wehrmacht entered the Prussia under polish occupation in sept 1939, by an agreement of UK and France with Poland signed in August 23, 1939. No conflict resulted when Stalin USSR entered Poland from North. Blessings +

  2. It would be good having a Six-flat Sleeve Valve engine for buses and trucks, with Bristol Air Cooled Sleeve Valve Cylinders. Mike Hewland, Car&Driver, July 1974, who worked making Bristol engines during WW II, indicated the Bristol SSV Aircraft engines could be revved up and down, same as a car engine. Its fuel economy is still unrivaled. SNECMA built some Bristol engines under license for the 'Noratlas' cargo airplane, installed also in the Spanish passenger airplane CASA Azor. Blessings +

  3. Harry Ricardo was the thinker, but Roy Fedden was the hand who brought Sleeve-Valve engines to what it became, the best Alternative Piston Aircraft Engines ever; the top development in SSV was the Open Sleeve, no junk head needed, sleeve acting as an annular piston, sending power to crankshaft, two stroke, compression ignition engine.
