In those tests, the suit held...
...last month from White. Sands, N. Mex., climbed for 102 miles before blossoming, folded its petals only after it dropped within 65 miles of the earth's surface. When it finally landed, Physicist Robert K. Soberman of the Air Force Cambridge Research Laboratory hoped to find a few micrometeor punctures in the three-layer sandwich of thin Mylar film and Plexiglas that lined the Aerobee's dust catchers. What he actually found was something quite different: during each second of exposure, some ten meteorites had hit each square centimeter. Most of the holes were microscopic...
