Infrared Challenges Radar’s Monopoly

Radar’s long monopoly in the fields of missile guidance, target detection, fire control and mapping is being seriously challenged by infrared, an old technique which has acquired some new tricks. There are some who predict that infrared, or IR as it is sometimes called, may largely replace radar within 10 years for missile guidance, target detection, and mapping if for only one reason: infrared can not be jammed.

Oversecrecy Defeats Itself, Scientist Says

We can distinguish three main components in the flow of technical and military information: first, the intercommunication of such information within industrial and governmental groups which are directly involved in closely related work; second, the flow of such information to the U. S. public at large, and third, its transmission to potential enemies of the U. S.

Letters

It was with considerable indignation that I read the article on p. 51 of your Feb. 4 issue entitled “New Interiors Designed for Viscounts.” I think you will readily agree that the most important feature of any commercial aircraft interior is the seats in which the paying passengers ride.

Bell System Permits Hands-off Landings

Buffalo, N. Y.—Bell Aircraft Corp. unveiled an automatic carrier landing system last week that allows hands-off landings in zero-zero weather.

MANAGEMENT

Washington Roundup

Results of a press conference can sometimes go awry, as evidenced last week by press and stock market misinterpretations of remarks made by Defense Secretary Charles E. Wilson. At his press conference, Wilson was asked just what factors would be considered in any possible change in the production rate of Boeing B-52 jet bombers.
