...about 450° F.), but it is remarkably successful against short attacks of extreme heat. It is used in 20 types of missiles, sometimes in the nose cones, sometimes in other hot spots such as the nozzles of rocket motors.

For an ICBM, which enters the atmosphere much faster, four inches may be needed. This thickness weighs, says Thompson, only one-fifteenth as much as a heat-resistant metal used for the same...
Even adults can lose themselves in Disneyland, where the past they have not seen melts into the future they will never know.

This information, processed by a complicated electronic brain, tells the missile the course it is following over the surface of the earth. It corrects its own course if necessary; it knows when it reaches the target and when to explode its bomb...
