They mat have kids at home, or in college, they know there’s no rush, the jokers building space capability started taking their sweet time after Apollo — that was a program operating against a deadline.
Funny how pressure clears the mind and gets results when nothing else will.
NASA changed after Apollo. They had issued mission specifications and allowed bidders almost free-reign to issue design proposals. After Apollo they were buying hardware and the aerospace industry was treated like a captive government arsenal.
That’s what my old boss used to call “no sense of urgency”.
