I think at the time, most folks at NASA expected moon landings to be commonplace within a decade.
Which is not a bad thing: given the immensity and ludicrousness of the Apollo accomplishment, I think NASA had quite a few nutjobs!
JIM LOVELL - I'm slated to be the commander of Apollo 14 sometime late next year.
CONGRESSMAN - If there is an Apollo 14... Now, Jim, people in my state have been asking why we're continuing to fund this program - now that we've beaten the Russians to the Moon. [1]
The chasm between what NASA wanted, pilots down, was to keep on its trajectory, but the politicians saw monies to tender.
It is true the main blame for our policies rests with those continuing to elect them. But those actually representing us and making the decisions are responsible also.
