...since becoming First Lady, Lady Bird Johnson visited the Appalachia section of Pennsylvania, where thousands of families live in the poverty of a dismal past. Last week she made her second trip-an excursion into the future at the Huntsville, Ala., Marshall Space Flight Center, where she saw the Saturn moon rocket...
...space center, engineers tried to explain their work to Lady Bird in terms meaningful to her. The 182-ft.first stage of the Saturn I is "three feet taller than the White House," its thrust is "equal to the power required to drive 100,000 Cadillacs," and the concrete in a 400-ft.-high test stand "would be sufficient to build a four-lane highway from Dallas to Fort Worth." Said Lady Bird: "Thank you for putting it into words I can almost understand...
...Ride with Aunt Effie. That afternoon, with fingers pressed to her ears against the thunderous noise, Lady Bird attended the test firing of a Saturn booster. "I never dreamed it would be that loud," she said, "It was fantastic. If you leaned up against this wall you just could feel it was quivering." Before leaving she recalled girlhood days in Alabama: "Until I was about 20, summertime always meant Alabama to me. With Aunt Effie we would board the train in Marshall and ride to the part of the world that meant watermelon cuttings, picnics at the creek...
...cross picket lines set up by the strikers. The railroad has a contract with the National Aeronautics and Space Administration to haul heavy building materials to the cape. As a result of the picketing, 30 projects worth $200 million were closed down, including construction of the site where the Saturn rocket moon shot will be assembled...
...Saturn's second stage, built by Douglas Aircraft Co., is even more sophisticated because of its uncomfortable fuel, liquid hydrogen. Space engineers admire LH2 because it provides better than one-third more thrust than kerosene, but it is hell to handle. It is so light (7% the weight of water) that it requires enormous tanks, elaborately insulated to keep the hydrogen from flashing to vapor. A long list of new materials had to be developed that would not lose their strength at the chilling touch...
