From Wikipedia [1]: > Landing men on the Moon by the end of 1969 required the most sudden burst of technological creativity, and the largest commitment of resources ($24 billion) ever made by any nation in peacetime. At its peak, the Apollo program employed 400,000 people and required the support of over 20,000 industrial firms and universities. I don't think that effort would have been considered sustainable. Although it's a bit of a shame that we seem able to find the cash for perpetual war instead. [1] https://en.m.wikipedia.org/wiki/Apollo_program https://en.m.wikipedia.org/wiki/Apollo_program
