Just over a decade after the first successful powered flight, fearless pioneers were flying over the battlefields of France in flimsy biplanes. As more airmen took to the skies, they began to develop tactics to take down enemy aviators, and by 1915, the best of these pilots were known as "aces." While profiling such early aces as the Red Baron, René Fonck and Billy Bishop, this history takes note of "the Few" who stood between Britain and invasion in WWII. Examining the incredible subsequent developments in aerial technology, John Sadler and Rosie Serdiville also question whether the era of the fighter ace is at an end.
