<s>[INST] One of the biggest objections to the initial proposal of using suborbital flights to space was not associated with the technology, craft or crew, but rather how the pilots would react. The use of suborbital flights would expose the pilots to higher g forces than any aircraft previously conceived, and many wondered if the body and mind of the pilot would be able to withstand the 15 gs of crushing load, particularly during high g turns and back to back launches. However, a group of test pilots and engineers devised and deployed a centrifuge machine in a Holloman AFB New Mexico. At this specially designed facility, pilots are secured firmly into something that resembles the front seat of a fighter aircraft. With the g-force sensing gauges and cameras covering almost every inch of the interior, the pilots would experience a prolonged period of intense g-force. The testing was started with lower g-programs, but progressively increased over several weeks to give the body needed time to adapt.[/INST]
