Scout (Israel)
In 1978, Israel Aircraft Industries (IAI) built Scout, a piston-engined aircraft with a 13-foot wingspan made of fiberglass. Scout's fiberglass frame emitted an extremely low radar signature, which, coupled with the UAV's small size, made it almost impossible to shoot down. The inexpensive Scout UAV could transmit real-time, 360-degree surveillance data via a television camera in its central turret.
