Gemini Capsule Boilerplate: How NASA tested the Spacecraft
John Williams shows a Gemini test capsule, called a boilerplate. These early spacecraft were used to test for function and astronaut safety. He shows how the Gemini Boilerplate Capsule in the Virginia Air & Space Center tested its parachutes to land safely in the ocean.

This capsule was used during simulations designed to train land and sea rescue crews active during the Gemini U.S. manned space flight program. The boiler plate capsule was used in place of an actual capsule to prevent the possibility of damage to the expensive flight-ready versions.
The name “boilerplate” signifies that the capsules are made of boiler plate materials, a general term for metals having a thickness of 9/64 inch or greater. Other names given to these capsules are “mock-up” or “dummy”. In some instances, boiler plate capsules were flown atop rockets, intended to test the flight dynamics of the actual capsules prior to expending a flight-ready version.
Uses
The Gemini Boilerplate Capsule was originally used as a rescue trainer for recovery forces during the Gemini and Manned Orbiting Laboratory (MOL) manned space flight programs. This particular capsule along with its shipboard cradle was transferred from the Redistribution and Marketing Branch at McClellan Air Force Base, California to the Air Force Space and Missile Museum in December 1969.
The Gemini Capsule was on display for many years in the museum rocket garden until it was removed for restoration on 19 July 2005. The contract for the restoration project was awarded to Keith Davidson of AirCorr Inc., Melbourne, Florida.
After restoration was completed, the capsule was returned to Cape Canaveral Space Force Station on 20 February 2006. It is one of a complete set of boilerplate capsules spanning the Mercury, Gemini and Apollo programs.
Wikipedia:
A boilerplate spacecraft, also known as a mass simulator, is a nonfunctional craft or payload that is used to test various configurations and basic size, load, and handling characteristics of rocket launch vehicles. It is far less expensive to build multiple, full-scale, non-functional boilerplate spacecraft than it is to develop the full system (design, test, redesign, and launch). In this way, boilerplate spacecraft allow components and aspects of cutting-edge aerospace projects to be tested while detailed contracts for the final project are being negotiated. These tests may be used to develop procedures for mating a spacecraft to its launch vehicle, emergency access and egress, maintenance support activities, and various transportation processes.
Boilerplate spacecraft are most commonly used to test crewed spacecraft; for example, in the early 1960s, NASA performed many tests using boilerplate Apollo spacecraft atop Saturn I rockets, and Mercury spacecraft atop Atlas rockets (for example Big Joe 1). The engine-less Space Shuttle Enterprise was used as a boilerplate to test launch stack assembly and transport to the launch pad. NASA's now-canceled Constellation program and ongoing Artemis program used boilerplate Orion spacecraft for various testing.
Gemini boilerplates
There were seven Gemini boilerplates: BP-1, 2, 3, 3A, 4, 5, and 201.[8] Boilerplate 3A had functional doors and had multi-uses for testing watertightness, flotation collars, and egress procedures.
