Dr. William R. Graham told a congressional committee that the suspected o-rings in the Challenger accident should be modified or redesigned. The manufacturer of the rocket boosters had submitted 43 possible modifications to NASA since February, and changes to the fleet, said Graham, would cost about $350 million. This was the first time any official from NASA had indicated a need for improving the seals since the January 28 accident.
The acting administrator also noted that recovery from the accident could cost the Nation $3.2 billion and replacing the Challenger would run another $2.8 billion. Not replacing the Shuttle, he warned, would restrict the fleet to military use and service flights.
