On Wednesday April 30th 1941 Frenchmen Denys Boudard and Jean Hébert stole a Jungmann from a German occupied airfield and flew it to the South coast town of Christchurch in England.
The story of this adventure was recently told by Marc Heighway and published on the "New Forsest & Hampshire Wartime Association" website. It makes interesting reading. A request to publish it here was denied, but you can read the article as posted by clicking here, or on the picture above.
Update from Ed Luckett:
Jungmann 4477 was subsequently flown by the RAF Telecommunications Flying Unit (TFU) as DR626, it was struck off charge in Nov 1941. Amazingly it is shown on the RS models Czech website as one of the variants of their 1/72 scale Jungmann models: https://www.rsmodels.cz/p/218/92206-bucker-131-d-in-foreign-services
Larry Harmacinski found the article and shared it with John LaBarre who passed it on to me.
