One of the most famous analog computers was the Norden bombsight, a mechanical analog computer made from gyroscopes, motors, gears, mirrors, levers and a telescope. It could both pilot the aircraft and determine when to release its payload.
According to the Computer History Museum, “Inventor Carl Norden sold his interest in the bombsight to the government for only $1. His invention proved critical to successful high altitude daylight bombing during WW II. Although considered a military secret during the war, some later studies refuted the claims of its great accuracy.”
