If the threat of nuclear war gets higher, I will buy a couple of these for my wife and I to hide under. For most every year in grade school we had fire drills, and air raid drills, or tornado drills. They always made us get under our desks to be safe in a nuclear strike or a tornado. It must be a very safe place. I remember they gave us a brochure and it had basic instructions on how to deliver a baby. I asked are all the adults going to be gone? Why do I have to deliver babies?
I like 13 miles as the nuke blast travels from Tinker, AFB. The home of Air Force maintenance, and the AWACS fleet. And a navy base!
A big hydrogen bomb there would likely be goodby time for me.
I really think the Mutually Assured destruction thinking will keep any aggressor from attacking us. Nuke em till they glow, nuke em till they glow!
