The author says that, but he admits he's also not an expert and more of an arm-chair historian. So his analysis might not be correct either.

It could all be false flag stuff:

•They actually were used for this stuff, but don't want to admit it.

•They weren't acctually used for this stuff, but want to make people think they were.

•They were designed for one purpose, built and paid for by that purpose, but then ultimately piggybacked being used by other services with plausible deniability.

Calibration has to be done somehow...

I don't think anyone is particularly concerned with putting out false info for 1960s-era spy photography anymore. But I could be wrong. Or simply part of the coverup operation.
