A strange looking craft -- an underwater glider, developed by Melbourne's enthusiastic explorers of the Victorian coastal seabed. Here, near Flinders Naval Depot, on Westernport Day, the first trial of the new glider, and it attracts plenty of attention. On board, one of the builders, Basil Johnson. Cameramen from the Sub-Aqua Group of the Australian underwater Centre go along to film its underwater performance.
Hand controls operate vanes and rudders that unable the glider to bank and turn like its aerial counterpart. It can dive to 30 feet and quickly rise. If the tow rope should break, the buoyancy tanks would soon bring it back to the surface. Cruising at three knots, the glider is easy to handle. Swimming exhausts air supplies in 15-minutes. Now, with no energy required, except simply to hang on, the diver's air will last up to 2-hours. Thus, greater range for exploring the underwater world -- with the chance of finding sunken walks, marine specimens and perhaps new fishing grounds.
Up and down again. A strange new glider goes through its trials. Successful, but already there are plans for another, more mobile glider, for Melbourne's underwater explorers.
Hard on the ears, but the windows still didn't flinch. So the wind velocity was boosted to one hundred miles an hour in on attempt to shatter the glass. But it still held firm. Both surveyors and architects were well pleased with the results of this unusual test at Melbourne airport.
