Great work by Popular Mechanics.
I had just had a discussion with a lib friend who had just seen some BS conspiracy film showing how what happened could have not possibly happened unless the building was filled with thermite, etc, etc. I'm like, "That makes absolutely no sense!' and she goes off with this scientific fact and not. I knew it was the same sort of science that says we never made the moon landing but did not have the correct scientific data available to prove what happened, had happened.
So now, armed with scientific data, I was able to respond to BS-science with the data that Pop Mech put together.
I am seriously considering taking out a subscriptioin to Popular Mechanics now.
