STRATOSPHERE SHELL PREPARED FOR NAVIGATORS
The little metal sphere that will be the stratosphere home of two men and scientific instruments for a few hours next month is rapidly being completed (SNL, May 27, ’33, p. 323). It is pictured on the front cover with Dr. Jean F. Piccard emerging at the unfinished vertex of the “orange peel” sections of dowmetal, the magnesium alloy one-third lighter than aluminum.
The sphere is truly a shell of the sky. Though 7 feet in diameter, its metal sheeting is only one-eighth of an inch thick. The weight is 200 pounds, compared with 300 for the sphere used by Prof. Auguste Piccard last year. There are to be two manholes and eight portholes distributed so that vision will be free in all directions. The floor will be made of dowmetal, and a space 4 feet square is being left for the occupants.
