History:
During the first weeks of the invation of Norway in April, 1940, the
frozen lake Jonsvatnet, 10km south-east of Trondheim, was used as a
temporary airfield by the axis forces. Værnes airport in Stjørdal
(approx. 30km east of Tr.heim) didn't have paved runways at the time,
and was unsuitable for heavy aircraft like the ju-88 and he-111, so the
lake was found to be an acceptable temporary solution to the problem.
According to people from the Norwegian museum of defence, the planes
stationed there were Messerschmitt bf-109, Junkers ju-87
"sturzkampfflugzeug/stuka", Junkers ju-88 and the Heinkel he-111. As
the ice on the lake got thinner, two German bombers, a Junkers JU-88
from KG30 and a Heinkel 111 from KG100 (the viking ship seen on some of
the pictures is the logo of Kampfgeschwader 100), were unable to
escape, and sunk to the bottom of the lake. The Heinkel was partly
disassembled before sinking. The fuel tanks of the Junkers had exploded
(I don't know how this happened. Either the Germans set it on fire when
they saw that it was lost, or someone attacked it), damaging both
wings. The little I have seen of the fuselage seems to be in good
condition.
There have been several reports about other planes crashing in the lake
during the war, but at the moment, the only one they have found is an
Arado 196 which crashed in the lake in '45.
