[James] Newman switched our suits over to their own battery power and oxygen. Then he started to depress the airlock. After a final purge of air from the airlock, we were in a complete vacuum. There was no sound. The cha-chunk I heard when they locked us in, I wouldn’t hear that now. I could bang on the shuttle wall with a hammer and I wouldn’t hear that, either; there’s no way for that sound to travel. The only noise I could hear was the sound of my internal cooling fan and some squeaking from moving around inside the space suit. My voice sounded different, too, because the sound wave travels differently through the lower atmospheric pressure. It’s at a lower register. I sounded like I was about to cut a blues album.
