Ballon (Balloon)

East Germany, 1979. After initially failing to flee from the East to the West in a self-built hot-air balloon, two families struggle to make a second attempt, while the East German State Police are chasing them. IMDB

I just watched this having recorded it on BBC4 a few weeks back, will be on the iPlayer for months to come.

Excellent 2018 film of this true story well told with edge-of-the-seat drama. Not sure if it has been drama'd up from the truth but it made a good film.

At the end there are lots of photos of the people and gear etc. which was clearly genuine - and then links to the falling of The Wall a decade later.

German with subtitles, but many parts of it are without dialogue. Well worth a watch - well acted and nicely shot.
