We had to dive under our school desks in the 50s when the threat was thousands of nukes going off all over the US. Many of those nukes would have been city busters, 20 megatons or more.

I remember too. I wonder how much help those desks whould have been to us should a nuke have gone off nearby.

Protection from flying glass, that's all they were. Later they had us assemble in inside corridors rather than stay in outside rooms for protection against fallout. We were sooooo doomed!
