Francis Rogallo, designed a collapsible delta wing which would deploy from within the hull of the shuttle after re-entry.
Although NASA did not pursue his proposal, aviation enthusiasts in the USA saw the Rogallo wing's potential for leisure flying. They developed his design into the first delta wing glider and the sport of hang gliding was born, spreading quickly worldwide.
Almost immediately, some of the Australia's early hang gliding pioneers tried various ways of attaching power units to their wings so they could take off without first having to climb to the top of a hill. After all kinds of experimentation, the forerunners of the modern flexwing microlight took to the skies in the early 1970s. Since that time, wing and airframe/engine technology has moved on rapidly.
Today's factory-manufactured microlights, powered by a choice of reliable two-stroke and four-stroke engines, are the result of years of design improvements within a framework of strict safety regulations administered by the CASA.
