One of the nice things about being an old ring knocker (I graduated from the Naval Academy almost 30 years ago) is that you can have a pretty useful set of highly placed friends. Some of them gave me enough information to confirm what I suspected. I cannot think of any way to say this gently - Dr. Jaczko was *wrong*. It is possible someone in his staff provided bad information, but it should not be all that difficult to see the problem with some simple, back of the envelop calculations.

I would think a guy with a PhD could do the math in his head - or at least enough of the math to ask for a verification of the analysis. I would expect someone who is in charge of a large, technically competent organization would double and triple check numbers and statements before going in front of C-Span cameras and a congressional committee and making statements and recommendations that distract the entire world from a real and growing food, water and shelter crisis.
