🏆 World No. 1 Stefan Langer flies the JS5 Rey for the first time! ✈️

What happens when one of the world’s best glider pilots takes the controls of the JS5 Rey for the very first time?

IGC World Ranking No. 1 Stefan Langer shares his first impressions of our 24.2 m Open Class glider — and gives an independent pilot’s perspective on its handling, performance and flying characteristics.

🎥 In this video, Stefan joins Uys Jonker for a closer look at the JS5 Rey, including the story behind its Solo self-launch system.

Then it’s time to fly! From a powerful self-launch to roll rate tests, airbrake performance and landing, Stefan puts the JS5 Rey through its paces.

And perhaps the most interesting question of all: How does a 24.2 m wingspan really feel in the hands of a world-class pilot?

A big thank you to Stefan for sharing his experience and first impressions!

Stefan Langer, Weltmeister und Nummer 1 der IGC-Weltrangliste, teilt seine ersten Eindrücke von unserem 24,2 m Offene-Klasse-Segelflugzeug und gibt eine unabhängige Einschätzung zu Handling, Leistung und Flugeigenschaften.

🎥 In diesem Video nimmt Uys Jonker Stefan mit auf eine Entdeckungstour rund um die JS5 Rey und erzählt unter anderem die Geschichte hinter dem Solo-Eigenstartsystem.

Dann geht es in die Luft! Vom kraftvollen Eigenstart über Rollraten-Tests und die Erprobung der Bremsklappen bis hin zur Landung nimmt Stefan die JS5 Rey genau unter die Lupe.

Und die vielleicht spannendste Frage: Wie fühlt sich ein Segelflugzeug mit 24,2 m Spannweite in den Händen eines Weltmeisters an?

Ein herzliches Dankeschön an Stefan, dass er seine Erfahrungen und ersten Eindrücke mit uns teilt!

HOW JS CHANGED GLIDING | Pilot Interview on the JS5, Wing Loading & the Future of Glider Manufacturing.

We sat down with Stefan Langer - World's No. 1 IGC Ranked Pilot, to talk about how Jonker Sailplanes changed modern gliding. With the JS5 open class glider right behind us, the conversation turned to the German manufacturers, why every sailplane is still built largely by hand, and where glider manufacturing is heading next.

@flyhenleyair , @jonker_sailplanes and @ontracktechnologies unveiled Peregrine Aerospace at the AISI 20-Year Commemoration, held during AAD 2026 at Air Force Base Waterkloof.

Hosted by the Department of Trade, Industry and Competition (the dtic), the event marked two decades of the Aerospace Industry Support Initiative, an initiative of the dtic hosted and managed by the CSIR. It also concluded Henley Air’s AISI-supported Bell 222/230 camera mount development programme.

During the ceremony, Henley Air Group Executive Chairman Dr Andre Coetzee presented a commemorative plaque to the dtic before signing the Peregrine Aerospace founding declaration alongside Uys Jonker, Director of Jonker Sailplanes, and AP Kotze, Managing Director of On-Track Technologies.

The Peregrine Bell 222 helicopter showcased at AAD 2026 this week is intended to be the first of three experimentally certified “Flying Test Laboratories” for ongoing design, development, upgrade and modernisation solutions. These aircraft will support the Henley 222 Legacy Twin project while providing a broader-spectrum test-platform service offering.

The partners intend to establish Peregrine Aerospace as a jointly owned, SACAA-approved aircraft design organisation. The proposed structure will combine Henley Air’s rotorcraft operational and maintenance experience, Jonker Sailplanes’ aircraft design and manufacturing capability, and On-Track Technologies’ precision engineering and composite manufacturing expertise.

The declaration records the partners’ shared intent. Corporate establishment, regulatory applications, scope of work and implementation remain subject to definitive agreements and the applicable South African Civil Aviation Authority approval processes.

From a dream on the ground to a world-class sailplane in the sky 🛩️🇿🇦

Niels Sundberg (Founder of Sun-Air of Scandinavia) saw something special in Africa - The beauty. The freedom. The extraordinary conditions for gliding.

And when two brothers had a dream, he believed in it before their first creation, the JS1, had even taken its first flight.

Und als zwei Brüder einen Traum hatten, glaubte er daran, noch bevor ihre erste Entwicklung, die JS1, überhaupt ihren ersten Flug absolviert hatte.
