see Karl's thread here... http://www.unexplain...howtopic=201881
"......we have started to look at residue from these cases...there are a number
of cases where we have metalic residue that has been analysed and we are beginning
to understand why it would make sense for an advanced technology to use these
particular metals in that particular combination"
Confirmation that there is residue/debris from UFO cases..?
Now I wonder what cases these are?
I saw that, and comming from Jacques Vallee makes it very interesting.
I cant wait to hear more about it.
