From the tunnel, smaller passageways slide off to the missile silos, each 165 ft. deep and 40 ft. in diameter. Other tunnels lead to the antenna silo, and to a circular power house 70 ft. below ground where four generators purr out power enough for a city of 5,000 people...
...first radioed from the capsule that he was ready to leave, then said: "Give me three or four minutes. I will be ready for you." Actually, he spent 11 minutes inside, presumably checking instruments. As one helicopter circled the capsule in an effort to cut the capsule's antenna before attaching a cable, Grissom announced suddenly: "I am going to have to take my helmet off and blow the hatch...
...land stations their already known positions. So far, it has not told any ships where they are on the ocean, but only because no ship at sea has the proper receiving equipment. Probably the first to get such equipment will be the nuclear submarines. When they poke a whip antenna above the surface to listen to Transit they will be able to tell where they are within 600 ft. A navigator who shoots the sun or stars with a sextant in good weather does an excellent job if he gets a fix that is accurate within one and a half...
...like to learn to navigate with their casual accuracy. In its latest effort to understand animal travel tricks, the Office of Naval Research has been loading homing pigeons with tiny, transistorized radio transmitters designed by American Electronic Laboratories, Inc. of Philadelphia. Despite four batteries and a 40-in. trailing antenna, each transmitter weighs only 2½ oz. and does not overburden an airworthy pigeon. For 20 hours, it sends out a signal that can be picked up by directional receivers tracking the pigeon to its home loft...
...Prevent Frying. The army is spending $75 million on Kwajalein, and the island already looks like the set for a science-fiction movie. Close to the coral beach, a circular, steel-mesh fence, 65 ft. high and 680 ft. in diameter, surrounds a rotating, triangular radar antenna, 80 ft. on a side. This electronic monster is named ZAR (Zeus Acquisition Radar), and when it sends its pulses into space to probe for incoming missiles, the fence will act as a shield to keep the powerful radio waves from frying all Kwajalein. Crewmen operating ZAR will go to work through...
