Patrolling the eastern seaboard in a dawn-to-dusk search for enemy submarines is a squadron of U. S. Navy blimps. Between patrols they nest in a big hangar on the New Jersey coast. The blimps carry bombs and machine guns, and, drifting at a slower speed than is possible for airplanes, can maneuver above a suspected enemy craft and drop their “eggs” accurately. Smaller blimps are used for training.
