Years ago(the 80's) a company I worked for went up on the ice off the coast of Greenland and drilled aprox. 250 feet down in the ice and retreved a WW 2 fighter plane that was one of 6 (if I remember right). the bombers were left behind also. They were known as the lost squadrin. They landed on the ice in the middle of a storm back in the 40s and were left there when the crew members were rescued.
i often wonder if enough ice has melted yet so the rest have sank to the ocean floor or is anyone keeping track as to possibly retreve the rest of them when it gets a little more economicly feesible. the reason the rest of the planes were left behind was a cash shortage. I also remember the fighters being quite rare and in surprisingly good shape
