We lost a couple of planes over the side when I was sailing the big blue seas, and I recall one of them was about 60 million and change. EA-6B had a arresting cable break upon landing and ended up in the drink. Pilots got out, and I suspect one of the first things they looked at was how deep it was under the keel. If it was a couple thousand feet, I bet they let it go. If it was recoverable, you can bet your next breath that they had DFC or one of his buddies down there. WAY too much gear on that thing that too many bad guys would like to have.
BIG difference between your pre-Peacemaker planes and the ones that routinely go in the drink now. Not only in terms of $$ but also in terms of intel.
I sure would like to dive that B-36. There is one at Wright Patt AFB in Ohio. One of the biggest planes you ever saw. If memory serves, it had the largest tire ever made for a plane put on it...before they went to multiple tires on a landing gear. Anyone ever gets a chance to go through Dayton Ohio, DO NOT pass up the chance to see your tax dollars at work at Wright Patt. Its better than the Smithsonian, if you are interested in military aviation. Takes a couple of days to see it all, and then you realize that there is more inside the gate. They actually had a second museum that not many people went to, that had all of the old Air Force One planes, and a bunch of planes they were restoring.
Well worth the visit.
Oh well, got sidetracked.
