I think it was designed for atomic bombs landing miles away, not to protect against direct assault. That is why we prefer our saferoom as a family retreat.
if i were to have a shelter/bunker I think i would buy one of those metal shipping containers they use on large ships to haul goods across the oceans in, bury it (basikly have a basement with the crate sitting in it, and somehow figure how to make the doors (prob have one welded shut) lock and unlock from the inside of the house, and then have another door like the old cellar door/stairs to the outside, and probably for just in case type problems have a round hole in the roof cut out with a ladder... obviously some basic tools such as a couple of hand says/metal blades, shovels and such would be kept to help get out if shtf big time... but mine would more likely be for tornado useage and maybe a safe room then if a nuclear blast hit or something... id rather go stand under it and be done.
I need to come up with something for me, I live in an apartment and being a college student will have no means to build a shelter soon. Best chance I have is my grandmas basement. Has a room in the back corner free of windows. Just probably have to barricade the door and hope for the best. sadly it is small though
I live in the middle of nowhere, and we own a couple of woods nearby with both a creek and pond at one of them. But sadly dad has told me the water table is too high to add on any sort of basement/cellar to where it would be totally underground. Would have problems with water leaks eventually. I'm thinking something partly in the ground, and partly above but covered with a mound of dirt would be the ticket for me.
If you're looking for storm protection and can get your grandma to let you make a permanent addition, there are plans out on the web for how to build a "safe-room" in a house. University of Oklahoma ought to have plans via their Tornado studies.
Im looking for more fallout protection then anything
