Well, I'm an engineering tech that works with exotic new materials including metals, ceramics, and proprietary compositions.. I absolutely believe that it was probably one of a hundred methods used to spy on a countries defense industry.
The CIA was very good too.
We needed tiatanium for the CIA program that produced the SR-71, and we had none domestically. We needed a lot of it and the soviet union had a large supply available. CIA made a series of shell companies that were very hard to trace back to anything even resembling the defense industry. Layer after layer of real companies that were covert suppliers to the us.
So the CIA program designed a surveillance plane to spy on the soviets, produced with titanium we purchased from, the soviet union.
