The film follows the story of two record-breaking endurance flights that used Cessna 172 Skyhawk single-engine planes and flew for 50 and 64 days respectively non-stop. These are the stories of pilots Jim Heth and Bill Burkhart who took off from Dallas Texas in 1958 and pilots Robert Timm and John Wayne Cooke in Las Vegas who sought to break Heth and Burkhart’s record and act as a flying billboard for Hacienda Hotel in 1959.
