The Passenger by Patrick A. Davis
Colonel John Quinn was a young, ambitious Air Force pilot who loved to fly -- until an Iraqi missile nearly ended his career...and his life. Three surgeries and four years later, Quinn is functional, but not good enough to fly. Assigned to the Pentagon, he's prepared to spend the rest of his career in a series of boring staff jobs. Then a military Learjet crashes shortly after takeoff in the rural farmlands outside Washington, and Quinn is called to lead the biggest investigation of his life.
