What are some of the lessons here?
1. Diving is associated with a degree of risk, which may include death.
2. Performing a pre-dive safety check (BWRAF) is a pretty good idea.
3. Eyewitness reports may be conflicting and contradictory.
4. All of us take facts and information, and filter it through our individual experiences and biases, and draw (possibly quite divergent) conclusions.
Beyond that, I am not sure what else I will learn. Having been on Molasses many times, with OD, I suspect I have biases that do not contribute to objective understanding. I also follow reports of general aviation accidents with some degree of particular interest. They are similar to reports of diving accidents. The newspaper accounts, and statements from supposed witnesses, frequently leave me thinking, 'Something is wrong here. The facts as presented don't add up.' But, that may be because I interpret them in the context of what I have done, and what I think I would do in the reported situation, and that view may cloud my understanding.
