Interesting - it does appear to be the test DuPont and Alcoa performed or had someone else perform. At least one of those articles provided links to some Alcoa or DuPont literature regarding the panels, and there is a reference to that test. (I believe that the company literature referred to the fact that the test would be performed in the future; if the articles are correct, they were written after the test actually was performed.) There is company-distributed literature available for consumers on one of the company's websites.
Edit: page 2 of the brochure at Alcoa info states: "The Miami-Dade Building Code stipulates that panel systems withstand the impact of a 9-pound 2x4 timber traveling at 50 feet per second." (Emphasis added). I don't have the knowledge to even speculate whether that is consistent with Margie's research.
