The primary Gemini-Titan 3 flight crew donned the training suits and full biomedical instrumentation, assisted by the space suit bioinstrumentation and aeromedical personnel who would participate in the GT-3 launch operation. As a result of this practice operation, it was established that all physical examinations, bioinstrumentation sensor attachment, and suit donning would be done in the pilot ready room at complex 16. The final readiness of the vehicle for flight was established by the Simulated Flight Test on December 3. For the launch vehicle, this test was a repeat of the Joint Combined Systems Test, but for the spacecraft it was a detailed mission simulation.
