Maintenance professionals conduct a preflight inspection and prepare a KC-46A Pegasus for a mission to refuel a B-1B Lancer May 17, 2021, at McConnell Air Force Base, Kan. This was the first time a KC-46 refueled a B-1 from an operational unit at Ellsworth and is a testament to the strong relationship between Air Mobility Command and Air Force Global Strike Command.
