This 88 feet long model heralded the renewal of airships in the current era. It flew in Australia during 1977-78, before the British AD-500 did so at Cardington. The Ardath was developed by MANtainer Pty Ltd, based near EssendonAirport, Melbourne. It used twin snowmobile engines of 45 HP each, and timber propellers geared to 1/2 engine rpm with toothed belts. The prototype MA-1 was bought by a Texan syndicate in late 1978, and achieved further development and flight operations in Texas.
