I'm visiting family in Kalispell, MT and it was mentioned to me, while we were driving around Flathead Lake that during WW2 a P-40 had made a forced landing on the frozen lake. When the ice melted, the P-40 sank to the bottom. I'm curious to know if anyone knows the details about the airplane, or where it might be? I would love to read the official report on this, if there is one. I appreciate any replies.
