From page 138...
... There are a number of rubble zones and craters at the Nevada Test Site. We could go out, presumably within the next six weeks, two months, five months, or whatever is required, and view remote detection schemes for finding out just where is a rubble zone and what is its extent.
From page 139...
... You have a tremendous moment arm, you know, getting from the horizontal to the vertical, but that has been worked up. It is an engineering problem that has been worked out for the multiple protective shelter system.
From page 140...
... You have to canisterize the missile such that it is a cold launch up to some point and then hot launch outside of that environment.
From page 141...
... DR. LINGER: Yes, and one thing that Joe LaComb said when he showed his movie was that the tunnel survived, but it indicated that it would of necessity have to be further protected inside for personnel and equipment, and I think he made that statement, and I think that is a very good statement.
From page 142...
... One of the advantages of the horizontal or near-horizontal egress out through a rock slope is the fact that you won't have this rubble lying there to worry about handling manually. SPEAKER: The problems of egress due to rubble, radiation, and other things that have been cited lead me to harbor the idea that the storage of a single missile should be in a corkscrew, convoluted type of opening where you could have it on rail and of a diameter so that the missile could be lowered to whatever point you want and a multiplicity of openings going out so that if one gets rubblized you have got four or five others.
From page 143...
... DR. LINGER: So you have a lot of potential egresses all of which go closer to the face than you would go for secured hardness, some of which you may get wiped out, and that is an alternative, and that is an alternative I am sure that will be considered, because it gives you the multiple egresses and it gives you a quicker out, than if you are at 2,000 feet to bore out.
From page 144...
... SPEAKER: I think it is fair to comment that the multiple-aim-point concept of digging the tunnels near the surface or all the way out, regardless if you try to harden them or put blast doors or something to shut them up, has been shown to be really not the right way to go because for every tunnel we dig all they have to do is add one more MIRV and it becomes cheaper for them to add a MIRV than for us to dig a tunnel, and that has been the downfall of the current shelter program in the past. That is why we tried to go to a totally benign environment until we have to start showing our hand and at the same time protect ourselves.
