The Adventures of Smilin' Jack is an aviation comic strip that first appeared October 1, 1933, in the Chicago Tribune and ended April 1, 1973. After a run of 40 years, it was the longest-running aviation comic strip. The strip was created by 27-year-old cartoonist and aviation enthusiast Zack Mosley, who had previously worked on the Buck Rogers and Skyroads strips. Mosley was a member of organizations that indicate his avid aviation research for his strip: Aircraft Owners and Pilots Association, Aviation-Space Writers Association, National Cartoonists Society, B.P.O. Elks, Silver Wings Society, OX-5 Club, and the Quiet Birdmen Fraternity for many years. On September 18, 1976, he was inducted into the Civil Air Patrol Auxiliary-USAF Hall of Honor.
