The Bumper was a two stage missile consisting of the V-2 first stage and the WAC Corporal
as the second stage. This was an experimental configuration to investigate unknown factors
which might be associated with stage seperation and ignition of the second stage rocket motor
at high altitudes. Six bumper missiles were fired at White Sands Proving Ground, New Mexico
and two were fired from Cape Canaveral (now Cape Kennedy), Florida.
