Flight, only flight,
GA = flying. Same same like hanglider pilots, paragliders, crikey even a meat dart under canopy. If you fly for a living, then so much the better for you. If you live to fly, so much *even betterer* for you :-)
Re the Junkers - those old girls were used to shift dredge components into Enga and other locations by Placer - amongst others - back in the day. Used to be some great stills at Placer Domes Canadian HQ, as well as the (now Barrick Gold Corp) Porgera Gold Mine (in Enga, Ipili country) of the Junkers bringing in improbably large and heavy looking gear, and sticking it down on equally improbable looking strips.
