When did Heinlein or anybody else suggest that such information would
not be available? You could give the Roman Empire complete plans for
the Minuteman missile complete with warhead, as well as complete plans
for all the infrastructure to build it and the infrastructure to build
the infrastructure. That doesn't mean that Carthage would be eating
nukes anytime soon.

Those ships are making a one way trip one time. How much "tech" do you
think they are going to have? A navigation system, propulsion system,
and life support, with most consumables severely depleted. How may
tractors are you going to make with that?

Alone, you would die of old age before you even started on the
infrasctructure to make integrated circuits. That assumes that you did
not simply resume the pre-technological ecological niche of humans--
felid food.
