RESCUE DEVICE
UNDERWATER SIGNALS SPECIAL LISTENING POSTS USE ON PACIFIC ROUTES NEW YORK, Jan. 26. The United States Navy’s underwater sound laboratory has announced the completion of five stations which will be established to rescue aircraft which crash in the Pacific. Two stations will be established in the Hawaiian Islands, two in California and one will be put aboard the destroyer escort Fieberling.
The project is based on a wartime discovery known as “Sofar.” A natural sound channel exists for three-quarters of a mile deep in. the ocean in which relatively faint sounds can be detected thousands of miles from the source.
The Navy intends equipping its planes with a one pound bomb which, dropped overboard from a crashed aircraft, will explode exactly threequarters of a mile down, thereby indicating the plane’s position to listening stations. The system will be extended to commercial airlines.
