WAC Corporal was a small liquid- propellant sounding rocket, developed
by the Jet Propulsion Laboratory for the U.S. Army. It used an attached
solid-propellant booster to clear the launch tower. The first WAC
was launched at White Sands Proving Ground, New Mexico, in October
1945. It reached an altitude of about 75 kilometers (45 miles).
Improved versions of the rocket reached 100 kilometers (60 miles).
