See www.universetoday.com/119984/13-more-things-that-saved-apollo-13-part-9-.... During our Hotel Mars segment, we discussed Gimbal-lock, the use of Passive Thermal Control, and the piloting skills of Jim Lovell in bringing Apollo 13 safely back to Earth. I'm quite sure you will find this to be an interesting discussion. You can email Mr. Batchelor or Nancy Atkinson through me at drspace@thespaceshow.com.
