The key to victory in World War II lay in wresting control of the skies from the Nazis. America's most courageous pilots hurled their underrated P-47 Thunderbolts time and again against the Luftwaffe's over-whelming power, and won. This is the true story of one of the greatest Thunderbolt aces of all, Robert S. Johnson: his training, his early failures, his brushes with death and his 28 kills that helped smash the German juggernaut. Step by step, dogfight by dogfight, manoeuvre by manoeuvre, he details daring aerial exploits against monumental odds with America's fabled 56th Fighter Group, a special breed of men who changed the course of history.
