hey ravensfreak....seattle museum of flight to check out what I say...in greenland a few years ago 2 planes from WW2 were dug out the ice, the rest are still there and still buried, the ice layers are called anual, meaning yearly like tree rings according to scientists, the guys who dug up the planes claimed they were under litteraly hundreds of layers, so how long were the planes there? they were there since hundreds of years before they were built and flown...
