Thanks Ray. I would have to seriously doubt Mitchell's comment then. (Not the reporting of it but the seriousness of his comment)

Kodak R&D in the 60s to 80s was about 20 years ahead of the pack from what we could discern in patents and the other literature. R&D was moving forward at a rapid pace, but was being kept as trade secrets for the most part. I wonder where Mitchell got this from? What gave him the idea?
