Master Sgt. David Jackson, the 28th Aircraft Maintenance Squadron production superintendent, salutes a B-1B Lancer that is being divested prior to its final launch from Ellsworth Air Force Base, S.D., Feb. 17, 2021. The divestiture of the B-1 is necessary in order for the Air Force to create an even more lethal, agile and sustainable force with a greater competitive edge in today’s fight.
