Apollo Command Module Boilerplate #19 was developed for parachute recovery tests. A boilerplate is a metal mockup of the same size as a flight production model. By using an unmanned boilerplate, the parachute recovery system could be evaluated without endangering human life. This boilerplate was first used for parachute drop tests at El Centro, CA in 1964. Upon later modification it became known as Boilerplate #19A and was used to test the VHF recovery antennae in 1968.
