Chasing the Demon: A Secret History of the Quest for the Sound Barrier, and the Band of American Aces Who Conquered It — A National Bestseller on Chuck Yeager and the Race for Supersonic Flight

NATIONAL BESTSELLER • At the end of World War II, a band of aces gathered in the Mojave Desert on a Top Secret quest to break the sound barrier–nicknamed "The Demon" by pilots. The true story of what happened in those skies has never been told. 

Speed. In 1947, it represented the difference between victory and annihilation.

After Hiroshima, the ability to deliver a nuclear device to its target faster than one’s enemy became the singular obsession of American war planners. And so, in the earliest days of the Cold War, a highly classified program was conducted on a desolate air base in California’s Mojave Desert. Its aim: to push the envelope of flight to new frontiers. There gathered an extraordinary band of pilots, including Second World War aces Chuck Yeager and George Welch, who risked their lives flying experimental aircraft to reach Mach 1, the so-called sound barrier, which pilots called “the demon.”

Shrouding the program in secrecy, the US military reluctantly revealed that the “barrier” had been broken two months later, after the story was leaked to the press. The full truth has never been fully revealed—until now.

Chasing the Demon, from decorated fighter pilot and acclaimed aviation historian Dan Hampton, tells, for the first time, the extraordinary true story of mankind’s quest for Mach 1. Here, of course, is twenty-four-year-old Captain Chuck Yeager, who made history flying the futuristic Bell X-1 faster than the speed of sound on October 14, 1947. Officially Yeager was the first to achieve supersonic flight, but drawing on new interviews with survivors of the program, including Yeager’s former commander, as well as declassified files, Hampton presents evidence that a fellow American—George Welch, a daring fighter pilot who shot down a remarkable sixteen enemy aircraft during the Pacific War—met the demon first, though he was not favored to wear the laurels, as he was now a civilian test pilot and was not flying the Bell X-1.

Chasing the Demon sets the race between Yeager and Welch in the context of aviation history, so that the reader can learn and appreciate their accomplishments as never before.

This meticulously researched account reveals the hidden story behind one of aviation’s greatest achievements:

• The Race for Mach 1: Go inside the top-secret, high-stakes program in the Mojave Desert where daring pilots like Chuck Yeager and George Welch risked everything to fly faster than sound.
• A Legendary Rivalry: Uncover the untold competition between two of America’s greatest aviators—one destined for fame, the other a civilian genius the military preferred to forget.
• Declassified Secrets: Based on newly declassified files and exclusive interviews with program survivors, this is the definitive account of what truly happened in the skies over California.
• Dawn of the Cold War: Understand the urgent geopolitical pressures that fueled the quest for supersonic dominance as the United States faced a new enemy in the Soviet Union.
• Expert Aviation History: Written by a decorated fighter pilot, Chasing the Demon brings a pilot’s perspective to the engineering challenges and human courage that defined the supersonic age.
