Sphere, Glider Feasible for Re-Entry

New York—Soundness of U. S. space flight efforts for years to come may depend on the choice of a vehicle to win the second round in the struggle to control space, members of the American Rocket Society were told here recently. Goal of this second round, placing a man in orbit around the earth and bringing him back safely to the ground, has tremendous scientific and propaganda value for the nation reaching it first regardless of the manner in which it is accomplished.
