Very cool -- I'm glad someone else could use the data!
BigML seems useful. The BigML decision tree looks quite a lot like the J48 tree result. I wonder if the performance (ROC) is closer to J48 than logistic regression. I couldn't see an option to cross-validate on BigML.
"The Right Stuff" by Tom Wolfe has quite a bit on this topic. The answer seems to be habitualizing or "adapting out" fear. According to the book, when John Glenn was launched into space for the first time, the situation was so familiar that his heart rate held at around 70bpm.
