Hugh Morgan, John Weal. German Jet Aces of World War 2. , Osprey, 1998.

Testing the He-176, then the He-178, the new weapon to enter Germany's arsenal has flown; the jet! The jets were a success, but Hitler rejected the new plane, trusting that Germany's airpower with the old Bf-109 will be enough to battle the Allies. What a big mistake! If he would have brought the jet into service, it would have dominated the skies over the Allied nations. Development on new jet aircraft still occurred, however, and the introduction of the Me-262 took place in 1943. The Me-262 was a truly awesome weapon, with about 100 mph. over the Mustang, and with four to six 30-mm cannon (there was even a type that had the 50-mm cannon!), the jet was truly amazing. But Hitler made his second mistake with the jet; he made almost all the `262s bombers! If he would have let Heinkel and Messerschmitt build jet fighters and bombers early on, the Germans would have won the air war.
