Aerojet SD-2 Overseer, an unmanned aerial vehicle (UAV) used by the US Army in the 1950s and 1960s
Many Holiness and Pentecostal denominations call senior church leaders "overseers" or "general overseers." This is a literal translation of the Greek word ἐπίσκοπος, which was borrowed into Latin as episcopus and ultimately became the English word Bishop.
