Unusual tunneling machine bores tunnels for missile base
Machine called Badger was used at Titan missile facility of Vandenberg Air Force Base to cut series of 10 ft diam tunnels 1300 ft through blue shale; unit cuts through ground with chisel shaped carboloy-tipped knives and braces itself against tunnel wall by two pressure panels; angling device governs alignment of machine; mucking operation slowed down tunneling.
