Against a backdrop of inadequate funding, misplaced priorities and a lack of manpower, American commercial aviation in the 1960s was in a perilous state. In July 1967, when a Piedmont Airlines Boeing 727 collided with a Cessna 310 over Hendersonville, North Carolina, killing 82 people, the industry was in crisis. This book reveals the true story of the investigation: what was left out and why.
