In 1921, Wesley May demonstrated the first aerial refueling capability by walking and climbing on the wing of one airborne aircraft to another, 1000 feet above the earth, with a five-gallon can of gasoline strapped to his back. May, with pilots Frank Hawks and Earl Daugherty, proved the concept of aerial refueling. This gave way to the Question Mark in 1929, and eventually evolved to the KC-46A Pegasus of today. It was a game-changing moment for global reach that started with an innovative thought, the fortitude to execute and a five-gallon can of gas. May, Hawks and Daugherty are shining examples of our ultimate competitive advantage…our people. Talented, multi-capable and digitally-adept Airmen are at the heart of achieving our National Defense Strategy (NDS).
