...this time, Lindbergh had become thoroughly bored with the press and publicity. Time and again, crowds would break through police lines to swarm up to his plane; more than once he swung the plane around to drive them back with the blast of his prop wash. In the four years after his marriage, he embarked on two world-swinging trips to explore aviation routes, the first across Canada and Alaska to Japan and China to dramatize the Great Circle course to the Far East (written up by Anne in North to the Orient), and the second across the North Atlantic...
...increase the intensity of X rays produced by a nuclear explosion, physicists can reduce the amount of uranium 238 in the outer layer of ABM warheads and add more tritium, which raises the temperature of the blast, to the fissionable material. As a result, nearly 80% of the energy released by the explosion of the new warheads, believed to be in the one-megaton range, is in the form of high-energy X rays. To extend the lethal range of these rays, which are quickly absorbed or attenuated when traveling through air, the ABM warhead will be carried high above...
Plasma Sheath. During the brief instant of the nuclear explosion (which lasts only five ten-millionths of a second), X rays traveling at the speed of light emanate from the center of the blast. Although their effect diminishes sharply at increasing distances even in the vacuum of space,* the X rays from a one-megaton blast are intense enough to destroy an ICBM caught within a sphere extending two miles from the exploding ABM warhead...
Neutrons produced by the ABM blast could also cause crippling damage at a range of about two miles. Penetrating into the ICBM's outer shell of uranium 238, they can produce slow fission, causing heat that may deform the warhead or set off its lens charges. The neutrons may also whiz into the warhead's core of uranium 235, causing it to explode in a premature nuclear blast while still hundreds of miles from its target...
...ICBM two miles from the blast will receive only one-quarter of the X-ray energy that hits a missile one mile away. At a distance of three miles, the impacting X-ray energy will be only one-ninth as large...
