I believe I've left enough in to enable you to find the original. As can be seen, cracks *have* been found on Columbia's ET door mechanism. From: yee@trident.arc.nasa.gov (Peter E. Yee) Subject: NASA Headline News for 02/22/91 (Forwarded) Message-ID: <1991Feb22.223645.6031@news.arc.nasa.gov> This is NASA Headline News for Friday, February 22, 1991 Kennedy Space Center launch team staff are proceeding with preparations for Shuttle Mission STS-39. Analysis of hinge cracks on Discovery's fuel line door mechanisms continues. As part of this ongoing analysis, a door closure test is scheduled for late this weekend on Columbia's fuel door mechanisms. Atlantis and Columbia have been examined to determine if similar conditions exist on their door mechanisms. No cracks have been found in the ET door mechanism on Atlantis, now scheduled to launch in April on its Gamma Ray Observatory deployment mission. Inspection of the door mechanism on Columbia has revealed three small cracks. Analysis of Columbia's situation continues. -- Chris Jones clj@ksr.com {world,uunet,harvard}!ksr!clj
