The Sling Squawk – June 2026
7 Jun 2026
Following their 73 flight hours from Johannesburg to AirVenture in July this year, I caught up with the Sling team in Oshkosh as they landed just minutes before the start of the Wednesday airshow. With EAA AirVenture probably the finest opportunity to launch the new high-wing variation of the highly-regarded low-wing Sling TSi, the South African manufacturer did this in spectacular fashion by flying the development prototype, as well as production serial numbers one and two, all the way from Johannesburg.”

The adventure continues! For once, there are no border crossings to navigate, no custom stops, and no major travel plans on the schedule. Just a quiet day at home. Naturally, that doesn’t last long… When Sling Chief Test Pilot, Riaan Denner, has an idea, you know things are about to get interesting. In this episode, Josh and Chelsea take to the skies over Johannesburg for some banner towing, go behind the scenes at the incredible Jonker Sailplanes factory, make a completely unplanned stop to meet a very special young zebra, and then set off on the next major leg of the journey — heading south towards Plettenberg Bay and Cape Town.
