JOINT BASE ANDREWS, Md. –
U.S. Air Force Staff Sgt. Joshua Morrison, a flight attendant with the 1st Airlift Squadron, designed and 3D-printed a smart tray to prevent salt and pepper shakers from spilling during turbulence on executive flights at Joint Base Andrews, July 21, 2025. Produced through the SparkX Cell innovation lab, the tray successfully modernized galley stowage systems, reducing cleanup time and improving presentation for distinguished visitors.
