MAN IN SPACE

A VAST amount of effort is being put into investigations on the possibility of human travel outside the earth's atmosphere. The problems to be solved before this can be made possible, if ever it can, are many and very difficult, and all sorts of people are going into print on the subject. An important paper has, for example, recently been published by the Surgeon-General of the United States Air Force, General D. C. Ogle,' under the title of "Man in a Space Vehicle", and a series of papers (not all so important), delivered at a symposium held at Denver, Colorado, by seven experts on different aspects of space travel have also been published." It is of interest to examine these expressions of fact and opinion.
