Bruce: When I talked with Tom Kaye in the stairway at the Burke Museum we talked about the findings on the tie being both alloy and pure Titanium. He had jumped to the wrong conclusion that it could have not been from Boeing as he thought we were only using alloy Titanium in the SST. He was not happy with my telling him he was wrong and how we were working with pure Titanium too (flame spraying it) in the 9-101 building. So, the sleuths had found both types of Titanium (plus other particles) on DB's tie. You need to report these things correctly or it drives me crazy.

Somehow, on the Citizen Sleuth website, they note a lack of alloyed titanium.
"Fact: All titanium used in aircraft is alloyed and the Cooper material was pure titanium.
Interpretation: Due to the lack of alloyed titanium, Cooper did not work in the aircraft industry."

Sorry, I have to agree with the Citizen Sleuth conclusions that Cooper didn't work in the aircraft industry.
