Randall Garrett, The Judas Valley
“ He thought of the bleached bones of the crew of the Mavis, and shuddered.It was something of an advantage not to be wearing a helmet. Even with the best of acoustical systems, hearing inside a helmet tended to be distorted and dimmed. The men couldn't hear him as well as he could hear them. And since they couldn't hear themselves too well, they made a little more noise than he did.A space boot came into view around a big rock, and Wayne aimed his needle-beam at the spot where the man's head would appear. ”
