I just now stumbled upon this very interesting article and history of two P-40's recently recovered from Russia. it always amazes me that the tires on 60-70 year-old aircraft are almost always still inflated! I wonder how many hundreds of lend-lease aircraft from WW2 are scattered across Russia waiting to be discovered, recovered, and restored? I hope you find this post interesting.
