I presented the latest information about the atifacts at the Roswell UFO festival early this month.
There is now a little more data to look at and it can be found at http://www.geosights.net/roswell.htm.
I appeared on the new National Geographic show called Chasing UFOs. The show did not keep their word about doing additional analysis on my metallic artifacts in order to prove their origins. The issue was chain of custody protcols. The National Geographic folks refused to follow good scientific investigative procedures. The show has OK entertainment value but lacks good detailed science. As the LA Times review says " too much Mulder and not enough Scully; I think that just about sums up the show.
