...medical front, Johnson cited pilot projects in West Africa that helped develop methods of immunizing young Africans against the area's biggest killer of children, measles. He said that 25 per cent of the susceptible population in then ten-minute old results of the successful 71-29 Senate cloture vote on the civil rights bill, he was interrupted by a thunderous, stadium-wide standing ovation...
...engines must run at high speed, developing too much thrust for a plane on its landing approach. But the research ship picks up no extra speed; its extra thrust is contained by big clamshell deflectors that can be controlled by the pilot. NASA's 707 drops down to the runway so slowly that its horizontal tail surfaces need special, upside-down flaps, which slant upward from the stabilizer's leading edge, to make the air flow over them properly at low speed...
...serves only for streamlining and control. When Alvin submerges, the water enters that thin skin freely. Inside is a 7-ft. sphere with walls of high-strength steel 1.33 in. thick to protect the crew from water pressure down to 6,000 ft. Its four viewing ports permit the pilot and observer to see ahead and below, and its three steerable, battery-powered propellers, two of which can swivel to point up or down, give high maneuverability and a top speed of about 7 m.p.h. Before Alvin tries deep and perilous submergence, it will begin practice runs this month...
...fight. Sheer physical stamina kept him going. His voice cracked and hoarsened, but he kept talking. At one point his determination might have led to disaster. Eager to keep a speaking date at a high school in Newport, he took his plane into a dangerous fogbound landing. The pilot of a following DC-3 press plane took one look at the soup below and more prudently turned back...
Guiding Cables. Below 200 ft. the glide slope beam of conventional ILS is not dependable because of ground interference and reflections from nearby buildings. In Britain, where fog is frequent and nasty, magnetic cables have been laid leading to the runways. Instruments enable a pilot to keep between the cables and glide down safely, even below 200 ft. But magnetic cables are not considered the final answer, even in Britain...
