Developed by Long Island's Gyrodyne Co. of America, Inc., the 1,600-lb., all-weather, buglike aircraft can lift off a destroyer, reach sonar-detected subs as far as 15 miles away, unleash two homing torpedoes and land back on the ship-all at the electronic command of shipboard officers.

What the porpoises said to each other, the Lockheed scientists have no way of knowing, but they are satisfied that the underwater travelers first picked out the man-made obstacle with clicking sonar, then talked the situation over with their whistling scouts before proceeding...
