It was in 1986 that McDonald, who worked at NASA contractor Morton Thiokol, refused to sign off on the launch of the Challenger space shuttle at the Kennedy Space Center in Florida on Jan. 28 of that year. His reasoning, according to a Los Angeles Times, was because he believed the cold temperatures around launch day could affect the rocket booster s O-rings, which keep gases from escaping.
