...maneuver an agile four-legged "quadruped" truck that is being developed by General Electric for travel over rough terrain, the driver controls the vehicle's front legs with hand-operated levers; the rear legs are moved by the driver's own legs, which are strapped into control braces. Feedback circuits allow the driver to "feel" the traction on the ground beneath...
Cutting Up the Slopes. The vast majority of snowmobilers use their sleds for recreation, find that one five-gallon tank of gas lasts all day and opens up untracked terrain that would otherwise be inaccessible. One 8-man group of diehards is even planning to embark next month from northern Canada on a three-week, 800-mile snowmobile trip to the North Pole, pulling equipment and supplies along on sleds behind them. There is a practical side to snowmobiles too. In the Western states and New England they are replacing snowshoes for telephone linemen, country doctors, trappers, game wardens, farmers...
...tricky combat terrain, U.S. troops have to develop all types of tricky tactics. A 32-man reconnaissance company of the 9th Cavalry Regiment has a new technique for getting out of their helicopters even before they land. In unsecured areas where the enemy may be lying in wait, the troops clamber out on the skids, and as the chopper flutters down to five or six feet above the landing area, they jump. They call themselves the "Headhunters...
...composite of the scenic grandeur of Grand Canyon and the barren desolation of the Badlands of South Dakota. But when it was flashed unexpectedly onto a screen at a meeting of the American Institute of Aeronautics and Astronautics in Boston last week, sophisticated space scientists and engineers recognized the terrain immediately. It was a spectacular closeup shot of lunar landscape. That photograph of the moon's Crater of Copernicus, said NASA Scientist Martin Swetnick, is "one of the great pictures of the century...
...bristling with machine guns, rockets and automatic grenade launchers; above the "gunships" circle jet fighter-bombers armed with searing napalm, white phosphorous and bomblets that can unleash deadly patterns of tiny steel pellets. In no other war has American weaponry so quickly matched the demands of a difficult tactical terrain. From the swamps of the Mekong Delta, where 30-ft. patrol boats packed with unsinkable plastic foam whisk along on water jets, to the shell-pocked "Rockpile" below the Demilitarized Zone, where six-barreled Ontos tracked vehicles rumble, the arsenal last week was in awesome action...
