Bob Hoover is one of history’s greatest aviators. His career spanned from barnstorming in prop planes, to dogfighting in World War II and then on to flight testing supersonic jets and performing spectacular aerobatic demonstrations. Hoover was the backup pilot for the Bell X-1, and flew the chase plane as his friend Chuck Yeager broke the sound barrier in 1947. Smithsonian’s Air & Space Magazine named Hoover Number Three on their list of all-time great pilots. (Special Two-Part Episode)
