Ok - the video of the discovery of the plane was in 1989 - but after 46 years (it crash landed in 1943) that’s still incredible!
Most planes that crash in forests are broken apart after hitting trees - but when this FW190 crashed 46 years previously the trees were just saplings - the forest grew up around it!
When they examined the FW190’s engine they found out why it crash landed - apparently oil pipes in the engine had been stuffed with a rag which caused the engine to seize a few miles into the FW190’s flight - by which time it was over enemy territory.
The German factory which produced the engine was using slave labour - so this is thought to be a deliberate (and heroic) act of sabotage against the Nazi war effort.
The reason the sabotage was not detected prior to the flight was that the FW190’s engines had only so many operational hours before they were due a rebuild (like race bikes) - so when the FW190’s (previous) engine had reached the end of it’s service limit it was removed from the aircraft (at the frontline airfield where the FW190 was based) and the fresh (sabotaged) engine which had come crated straight from the factory was bolted in in its place.
The aircraft was recovered and has been restored.
