There was someone who was asking questions during the course of the flight - that seemed to not realize, no matter how many times they were told, that Columbia did not have its arm installed for its last flight.<br /><br />For when SK returns with a new name, consider this:<br /><br />(1) Because there was no arm, there was no way to work on the exterior in a secure way. <br /><br />(2) There were no materials available for a patch to the RCC. To date there is still no way to patch damage to the leading edge RCC panels - the damage that Columbia suffered. <br /><br />So trying to extrapolate from what was done with Discovery to Columbia is erroneous.<br /><br />The only argument that can be made is that NASA should have employed more of the more limited means that it had available to look at the shuttle. It is possible, though by no means certain that spy assets might have seen something.<br /><br />If they had though, fixing Columbia, even now, would be a non-starter. The only scenario for saving the astonauts would have been a rescue mission. Keep in mind this has a lot of its own risks, including prepping a shuttle in record time, and hoping that whatever happened to Columbia doesn't happen to the next one.<br /><br />Wayne<br /><br />p.s. I know this is a mistake. Folks like this almost always dismiss something that disagrees with their thinking as covering for NASA. Oh yeah, and its way off topic. <div class="Discussion_UserSignature"> <p>"1) Give no quarter; 2) Take no prisoners; 3) Sink everything." Admiral Jackie Fisher</p> </div>
