We welcomed Lee Hutchinson to the program to discuss his recent article, "The audacious rescue plan that might have saved space shuttle Columbia" which you can read at http://arstechnica.com/science/2014/02/the-audacious-rescue-plan-that-mi.... Note that Mr. Hutchinson said he found the possible rescue plan spelled out in the CAIB report in seldom discussed Appendix D13 of the report. In questioning Lee, we also learned that the plan did not exist real time with Columbia but was actually requested as part of the Columbia Accident Investigation Board's work. In the first segment of our 1 hour 28 minute program, our guest told us why he wrote the article and how he noticed the possible rescue plan back when he was tasked with reviewing the CAIB Report. During this segment, our guest described all parts of the plan and we discussed the likelihood of it having worked had it been implemented. Lee also discussed probable & significant timing issues with parts of the rescue plan making it unlikely to have been implemented had it been a real time plan under consideration. It was dependent upon too many things happening precisely on time and schedule, something that was not always possible with shuttle launches. Lee also went over the specific crew training issues that would have been required, plus issues in using EVA suits and getting them to and from Columbia for the astronauts to use. Listeners asked many questions including questions about NASA management at the time, risk averseness, & the NASA culture. Lee was asked about the comments & feedback he received from writing his article. As the segment ended, Mr. Hutchinson discussed plane change maneuvers and the significance of the orbital inclination of Columbia and the ISS. In the second segment, a Cleveland listener ask for Lee's thoughts on SLS-Orion. Lee & I talked about this & the NASA culture plus the need for heavy lift assuming there are missions for it. He was asked if the shuttle could fly without pilots, then we went back to SLS. He also told us about his interest in the redesign of the F1 engine. You can read his articles on the F1 here: http://arstechnica.com/science/2013/04/how-nasa-brought-the-monstrous-f-... http://arstechnica.com/science/2013/04/new-f-1b-rocket-engine-upgrades-a.... Lee received several email questions regarding the foam strike on Columbia & foam modification efforts. He was also asked about the shuttle repair kit which was carried on subsequent shuttle flights. Benny asked if a 3D printer on board could have made the materials to repair the Columbia damage. Please post your comments/questions on TSS Blog above.
