When NASA's space shuttle re-entered the earth’s atmosphere the ship endured immense amounts of pressure and heat. The ship was built in such a way as to shield the astronauts from these elements. Even with the ship doing its job, the astronauts still experienced up to 3Gs (gravitational forces). This was only one aspect - the physical - of re-entry that the astronauts had to endure.
