Yeah, I Figured that the North Atlantic wouldn't be too kind to anything that sits at the bottom. I imagine the recovery would also be thwarted by choppy conditions and bad weather (that's just what I picture up there as I've never been).
James, my first idea when I learned of these 20-25 P-39's, and now several p-40's and P-51's; is I only thought of the historical significance of the artifacts and didn't considered them as a way to make profit from resale. It's really nice to see so many P-39's being restored at Wangaratta. I can't wait to see them all take to the air. By the way, where are all those airplanes going to end up? Do they already have owners, or are they going to be for sale when completed?
If I had the means to recover them I'd not care so much about getting them all flying, but more interested in simply preserving them. I can only imagine how much easier it is to preserve an artifact like an airplane on solid ground, in a building, compared to on the sea floor.
The depth that I figure they'd be at would be anywhere between 150 ft. and 6,000 ft. I'm no expert, but I think that the deeper you go the more acidic the water gets, being very bad for preserving metal artifacts. Correct me if I'm wrong.
With regards to the depth, I used a really rudimentary map I found on Google that mapped the North Atlantic. I have no idea what the routing was for the supply convoys, but if I did have a better idea I could probably figure out a more accurate depth of expected sunken ships.
Maybe I'll call Uncle Bill Gates and see if he'd like to pitch in.
Cheers,
