摘要

The Columbia Accident Investigation Board is considering whether small but critical "gap-seal tiles" that bridge the or-biter's reinforced carbon-carbon leading edge with larger tiles on the lower wing surface could have failed after being struck by foam from the Lockheed Martin external tank. Damage to these gap-seal tiles could have opened a breach that would have been pointed directly into the hypersonic plasma flow as Columbia was pitched 40-deg. nose-up for reentry, said board member Rear Adm. Stephen Tur-cotte, commander of the Navy Safety Center at Norfolk, Va. The panel held its first hearings last week, adding three new members, including former astronaut Sally K. Ride. Ride was the first U.S. woman in space and was also a member of the Challenger accident board 17 years ago (see p. 31).
