There is a website http://warrelcis.eu that has a ton of this stuff but the most surprising is a Russian pilot of a WW@ Lend Lease Hawker Hurricane that crashed in the Swamps around Murmansk and when located and the aircraft excavated, his body was found preserved due to the lack of oxygen and the tannic acid of the swamp water.
His body was supponificated or turned into a type of gelatin soap. You can see the detail of his face and his uniform is perfect. Only his feet are missing where they hit the rudder controls in the cockpit and were cut off.

The Northern areaches of Russia have yealded a huge number of aircraft and armored vehicle recoveries. P-39 Aircobras from the bottom of a lake in very restorable condition (even the tinned USA supplied Meat stored in the plane was in ok shape).

I have seen a lot of this type of recovery from Northern Russia and Siberia on several websites. Since some of the relic hunters now use GPR instead of the old method of driving metal rods down 10 to 20 feet hoping to strike a find, I expect more will be found.

Remember the USSR fought HUGE battles on THEIR territory, in areas that were closed for the next 60 years. Karelia in the Eastern Baltic is still FULL of WW2 sites. The remains of the dead are there as well. If you step off the road into the woods you can still be blown up by land mines.

In Poland, they find large mass graves in the countryside when digging for a construction project (4000 +) and my co workers tell me the German Autobahn from Germany toPoland was still in the same condition in 1990 as it was in 1945.

And of course parts of Lybia and Algeria are still covered with British and German land mine fields from WW2.
