re: #444 McSpiff

Agreed with most of your post, with the exception of the last paragraph. There are still many, many project that little to nothing are known about. I’m thinking in particular of a few of the newer spy satellites, that other than suspected launches, we really know nothing about.

I agree with you there, but I was talking more of large flying machines and thousands of people involved. The design capabilities of the lenses on a spy satellite probably don’t need to be known by more than a handful of designers. Even those who make it according to engineering specs would not need to know what it can do to any great degree.
