this weather must be susceptible to accurate forecasting several days in advance. The localities affording the type of weather which meets these specifications should be examined and evaluated as atomic prov—ing grounds in the light of other requirements. Real estate of a satisfactory type and in ample amounts is a material requisite in any site under consideration. The number of personnel involved in the experiments, the vast quantities of equip- ment employed, the space necessary for the location of scientific measuring devices, and the relatively large "safety zone" required - all of these factors influence the size of the area which must be available. | One or more air strips capable of accommodating numerous heavy aircraft must be provided and supported by reasonably complete base facilities. It is desirable, of course, that the land on which the site is located be of little value for other purposes. There is reason to believe that each succeeding test may surpass those of the past in magnitude; consequently, the search fora suitable area should be conducted with consideration given to the need for future expansion. Finally, the selection of a site should be influenced by the question of logistics. Even in the most ideal circumstances, logistic support required for atomic proof-testing assumes huge proportions. When such testing occurs in an area which can be supplied only by water and air transportation, the problem is magnified greatly by the number of personnel involved in support of the transportation effort itself.
