WASHINGTON (AP) — A large pool of dark liquid festering on the floor. No fresh air. Computer displays that would overheat and ooze out a fishy-smelling gel that nauseated the crew. Asbestos readings 50 times higher than the Environmental Protection Agency's safety standards. These are just some of the past toxic risks that were in the underground capsules and silos where Air Force nuclear missile crews have worked since the 1960s. Now many of those service members have cancer.
