U.S. Air Force Staff Sgt. Joshua Morrison, a flight attendant assigned to the 1st Airlift Squadron, positions the new smart tray into the galley stowage cart aboard a C-32A at Joint Base Andrews, Md., July 21, 2025. The 3D-printed smart tray modernizes the previous system to securely hold salt and pepper shakers and mitigate spillage during turbulence on executive flights. (U.S. Air Force photo by Staff Sgt.
