(last post for awhile again guys so if I don't respond it's because I didn't get to read the responses, etc.)
The guys trying to recover the aircraft could have some serious problems. I can't remember where I read it but it was an article written by the leader of a team of guys who looks for 'salvage' (sunken ships, aircraft under water, etc.).
The problem with any argument the recovery people could make is that the aircraft are still the property of the U.K. or U.S. military. The article told of several occasions where the salvage guys recovered something (once I think it was a TBM) and once they had recovered it the government stepped in and said "Thanks we'll take our aircraft/wreckage/salvage now" and compensated the salvage guys pennies on the dollar for their expenses. Of course part of the blame rests with the salvage guys because they didn't check with the government first and knew that 'post recovery seizure' was a possibility.
What I am surprised at is that I haven't seen the opinions of the surviving families listed, mentioned, etc. If they are at the bottom of a lake and it was a training accident I think the final word would have to come from any surviving family. If it was my Dad, I think I'd say recover the aircraft make it flyable and have my Dad's name and wartime rank on the side forever and a picture of him in the cockpit so everyone remembered where the aircraft came from.
The Arizona is a different case in my book - it's a landmark that's a big part of history that happens to contain the graves of a bunch of brave Sailors. But even the Arizona will be gone before too long the sea is eating away at her.
