Thanks! However, this seems to be an economic estimate by one guy that sounds plausible enough but can't be fully assessed by a non-expert. Although it's useful evidence, it's not very helpful for determining the actual expert opinion at the time.

The 1973 GAO report[1] mentions the same issues. It does not reach a final judgement, but recommends Congress should examine the planned missions carefully. The recommendations and conclusions sections is a relatively short and easy read. I get the impression (though it could be my bias) that it is written skeptically.
