After several years in service the wings showed signs of stress, corrosion and cracks, and it was decided to replace the wings on only a few aircraft and retire the rest because it was financially prohibitive to repair the entire fleet. In the meantime NASA had contracted the Air Force to operate research missions that were part of the Earth Resources Technology Satellite program (ERTS). NASA chose the WB-57F for its High Altitude Research Program. The two WB-57's were then assigned the numbers NASA 926 and NASA 928
