Columbia's flight in early January, NASA announced, was made with a flawed backup o-ring inspectors had overlooked. A disaster similar to the Challenger accident four years ago could have occurred if the primary seal had failed. Inspectors also missed inferior welds on a critical pump that supplied one of the Atlantis main engines with fuel. The problem was corrected while on the launch pad in preparation for the upcoming February 22 launch. (OH Sen, Feb 1/90; Fla Today, Feb 1/90)
