History
There were numerous experiments involving jet propulsion for aircraft just prior to the outbreak of World War II, with Germany, Britain, and Italy leading the way. The United States, the Soviet Union, and Japan were somewhat late in starting, but by the end of the war, only the Russians and the Japanese had failed to fly a jet powered prototype, and Germany, Britain, and the United States had begun to produce actual jet fighters, with Germany and Britain in the lead.
This text, the second in the series by Osprey, covers the Gloster, Heinkel, and Caproni prototypes. Osprey’s previous book, X-Planes, Luftwaffe Emergency Fighters, covers most of the Luftwaffe developments, although none of these types reached actual production.
