For anyone who’s interested – here’s a post (from the Aus HG history FB page) by one of our (SAHGA) founders – Dave Wearing-Smith. It tells the story of how SAHGA came to be formed in the mid-1970s - & includes the few years before that – when pilots would have to build their own gliders & teach themselves to fly..

Dave WS was in the 1976 SA HG team -alongside Wayne Blackmore & others - for the Blue Stratos comp at Thredbo (pictured below).
