The treasure in the tragedy of AF 447 is what it can teach us.

Thank you, David Learmount at Flight Global, for calling for dialogue. Thank you Wood's Hole Oceanographic Institution and Bureau d’Enquêtes et d’Analyses for recovering data we can all work from.

Thank you, David, for offering to share the blame. All of us share the blame, all the way down to the passenger who wants a cheaper flight. But in the end, blame is irrelevant. Blame only serves economic interests which demand simple answers. These answers will not be simple.

Let us all be brave and try to speak truth as we see it. Let us all bring our training and experience to bear on the recovered data and mine it for lessons and solutions.
