1. Did the material continue after the Japanese interdiction by air?
2. If so, were the lessons learned used 20-30 years later?
My guess is "yes" to both.
I was just trying to catch up with you guys on the content of the article at #4 and discovered a screw up. The articles headed “Japanese Deliver . . .” and “Stimson Asks . . .” both begin on the front page and continue on page 4. When I set them up for scanning I switched the inside parts. So the end of the first article is on #5 and the Stimson article ends on #4. Sorry about that.
