The Boeing Company is fully committed to the safety of the space shuttle and its astronaut crews. We appreciate the efforts of the Columbia Accident Investigation Board to determine the cause of the accident and to recommend steps for shuttle return to flight. The Board's final report is very thorough, and is deserving of equally serious thought and response. Boeing will, therefore, continue to work with NASA and United Space Alliance to evaluate those recommendations, improve our processes, and support the timely and safe return of space shuttle operations. We recognize that the space shuttle remains key to the assembly and full scientific utilization of the International Space Station.
