Exactly. And what about Good 'ole Thomas Jefferson... the
"yankee professor" quote. Also we would never fly, or go to
the moon. This thread got me thinking. What kind of stuff
could actually make it to the earth? What about ice falls?
Could cometary parent bodies produce them? There have been
falls in previous centuries, so I assume aircraft could be
ruled out, and that the reports are not all "stories."

Now to present day: I heard reports (I believe one was from
LANL) about "foil" that fell after the El Paso 10/9/97
bolide. I remember hearing a report that sheriff deputies
drove through this stuff, but nothing was ever found.
Appariently, it completely sublimed. How the hell is it
possible for "metal foil" to completely sublime, or for that
matter, any solid meteoritic debris?

I am aware of phase diagrams, triple point, ect, but this
still doesn't seem right, given the short time spans
involved and the apparient solidity of the debris. Can this
happen? Anybody know?

Thanks,
Brian
