About this book
Aimed at boys, Harry Delacombe’s illustrated guide combines the history of balloons and airships with explanations of flight and aircraft design. It describes how compressed hydrogen could speed balloon inflation, while specially joined goldbeater’s skins helped keep the gas from escaping. In its account of early airship trials, Renard and Krebs complete a return flight of nearly five miles in 23 minutes. A diagram of a kite makes the discussion of lift concrete, showing how its angle and bridle help the wind raise it.
