Map projections speed SAC war-room display (Mar, 1963)

Map projections speed SAC war-room display

Less than 30 seconds elapses between receipt of information and the time it is flashed on a vast screen where it can be studied by the battle staff in the Strategic Air Command’s war room near Omaha, Nebr. The new system in the underground three-story, reinforced-concrete command post at Offutt Air Force Base works this way: The printed sheet with critical data on it is passed through a copying machine that transfers the data onto a plastic transparency. One of six projectors then projects this through an overlay map. The transparency film was developed by Minnesota Mining and Manufacturing Co.

Transparency projection replaces a system that required wheeling out of up to 40 8-by-20-foot plastic panels mounted on trolleys. Data had to be transcribed by hand. The same number of maps and charts on 10-by-10-inch overlays can now be kept in a file folder.

    Gee this dashes all my “War Games” illusions.

    “You can’t fight in here! This is the War Room!”

    So, Minnesota Mining and Manufacturing is 3M. (I saw a very old roll of scotch tape 4 or 5 years ago so old it had the full name on it.)

    This was the temporary SAC command center before the Cheyenne Mountain Complex opened in 1966.

    @JMyint – for a second I thought you were commenting on this.
