MacDill Air Force Base, Fla. -- Staff Sgt. Michael Johnston, an aircraft metals technology machinist, scans the hand of British Air Cadet Aaron Thompkins, of Enfield, Britain. Johnston demonstrated the Air Force's ability to scan a piece of equipment, or a human hand, into a computer system so it could be engineered and re-created. Fifteen cadets and 7 staff members from the British Royal Air Force Cadet program toured Macdill for a day, learning about the Air Force Reserve.
