Fair one. But my career background means there was no room for speculation. Investigation, yup. Guess, definitely not. Killer. So trained habits like that have followed me into my second seafaring carreer and I've no regrets about that.I’ll always mildly disagree with your dislike of speculation - I think we all learn something from discussing all the possibilities and reveal a lot about ourselves and our individual biases and fears. We rarely learn anything about the incident itself.
