The plane sank largely intact to the bottom of the lake, where it stayed until 1952, when it was raised, restored and exhibited around the country. In 1966, it travelled to St Gallen, where a businessman planned to build a “bomber theme park”.
This never materialised, so in 1970 the plane went on display in St Moritz. But after a few years it was blocking a building development; since no buyer could be found, it was turned into scrap metal despite being of historical value.
