The article was written by Alejandro Rojas and explored the work of Frank Kimbler, a teacher in Roswell. It seems Kimbler found some debris, suspected it may be from the famous crash, and subsequently had the debris analyzed.
As can be gathered from the title of the article, Rojas suggested no further analysis is necessary and that the debris is certainly “not from Earth.” Frank Purcell offered some contradicting peer review, the gist of which is that Rojas' claims are premature. With Frank's permission, I post his comments:
Isotope Abundance - observed Abundance - naturalMG24 79.1 +/- 0.5 78.6MG25 10.1 +/- 0.5 10.1Mg26 10.5 +/- 0.5 11.3
I would also like to see Open Minds or others follow up on the Kimbler debris, eventually giving us the rest of the story. One way or the other, I appreciate Frank offering qualified peer review. Ufology could use more of this kind of analysis of such circumstances and those who report them.
