Jonkers JS5 – Discovering the Namibian Sky

The latest flagship from Jonker Sailplanes, the JS5 Rey, has successfully completed its first flight in Namibia - in the world-famous thermal oasis of Bitterwasser. Thanks to excellent weather conditions, several 1000-kilometer flights have already been achieved.

With the JS5, Jonker Sailplanes sets new standards in the open class. The development focused on a lightweight structure for optimum climbing in weak thermals and exceptional glide performance at high speeds with a wingspan of 24.2 meters.


We are excited to see what record flights will be possible with this glider in the future!

The Long Journey to Africa

In early September, the containers holding the gliders for the 2026/27 season were loaded in Waghäusel. Transported by trailer, truck, and cargo ship, the gliders are now on their long journey to Namibia, to the Bitterwasser Flying Lodge.

Two new world champions are heading to Bitterwasser!

The Bitterwasser Flying Lodge was the main sponsor of the Junior World Gliding Championships, where from August 2 to 17, 2026, around 80 pilots from 22 nations competed for the titles in the Standard and Club classes. The grand prize for the JWGC winners was a one-week stay at the lodge, including travel and an airplane.
