The SpillRaider II trailer is stored outside of the 28th Civil Engineer Squadron headquarters at Ellsworth Air Force Base, S.D., Sept. 17, 2018. The SpillRaider II trailer is equipped with a larger pump than SpillRaider I, and requires a larger air compressor like the ones typically be used by the 28th CES.
