The N-9 seaplane Mirick was using dated back to a 1915 flying-torpedo project led by Lawrence Burst Sperry, inventor of the Sperry gyrostabilizer. Sperry's "unpiloted" plane differed from Mirick's primarily in that Sperry's had been supposed to navigate by preset automation rather than radio control.
Also included on the tail were a flare, radio receiver, antenna, gyrostabilizer, and rudders.
