An ambitious project, a challenging reality – discover the story of the LIS glider [ FILM ]

DATE:17 / 07 / 2026

Following on from the Swallow, the Cuckoo and the Pirate, it is now time for the next hero in the series ‘Downwind and Upwind – Civil Aviation’. In the latest episode, we present the story of the SZD-25A LIS glider – a design intended to replace the popular Mucha and which looked set to be a sure-fire success. Despite its promising design, however, it failed to live up to the expectations placed upon it.

The Lisa project was based on ambitious goals. It was intended to replace the SZD-22 Mucha Standard training glider, whilst being technologically simpler and cheaper to produce. On paper, everything looked excellent. But what was the reality?

In the latest episode, we discuss, amongst other things, the circumstances surrounding the creation of the Lisa, its construction, design features, manufacturing flaws and interesting facts. We invite you to watch the film.
