It's either in Popular Science or Popular Mechanics magazine about four
or five years ago.(I snail mail subscribe to both magazines,I have that
particular magazine floatin around here somewhere.I am the most
unorganized dude on earth,it would take me ten years to dig up that
magazine) A woman whom retired from NASA,she said,,, NASA! YOU ARE
BROKEN!

Go look around in your local area libraries for that magazine,with what
she said on the cover of that magazine,,, and there is a big article
about that in the magazine too.
