The story of the evolution of Heinkel's heavyweight bomber, described in this volume, is one of genius, disaster and despair. The He 177 was conceived as a long-range heavy dive bomber, a big-brother to the Stuka and it was hoped to become one of the pillars of the Luftwaffe's armament. It incorporated many novel ideas, such as two engines powering one propeller, but was plagued with teething problems and unreliability that caused the deaths of many test pilots and led to a small production run.
