@michael_w_busch @Junco @cstross The space-rated ones wound up with a "direct lunar return velocity into a steel mill" spec. Which didn't happen (though it would have been an interesting report from the night shift about the hole in the roof...) but Apollo 13 did, and as I recall they fished those out of the Pacific and flew them again.

Which does seem like "sufficiently sturdy" was achieved.

@graydon @Junco @cstross Apollo 13's RTG was never recovered - it was deliberately dropped in 10 km of water. The RTG from the Nimbus B launch failure in 1968 was recovered from a few hundred meters down - en.wikipedia.org/wiki/Nimbus_B .

The redesign was after the Transit 5BN-3 launch failure in 1964, where the older RTG disintegrated on re-entry.

@michael_w_busch @Junco @cstross Thank you!

I do find it kinda silly to be paralytically worried about 4 kilos of Pu in the atmosphere given the amount scattered about by weapons testing.
