Pat revisits one of aviation’s great unsolved mysteries: the disappearance of Amelia Earhart and navigator Fred Noonan during their 1937 attempt to fly around the world. Joined by retired Lieutenant Colonel and airport safety and security auditor Kevin Byrne, Pat digs into the navigation challenge of finding tiny Howland Island, the limits of 1930s radio direction-finding, and why a missed heading or changing winds could have proved fatal.
