I trust you. The Navy? Not as much.
Please note that it has been reported that personnel of both MDSU-1 and MDSU-2 were responsible for tearing PBM-5 BuNo 59172 in two during training exercises in 1996. As mentioned, I would personally prefer that the EXPERTS of the Navy's MDSU's gain their expertise practicing their trade on historically-less-significant airframes.

That was 22 years ago, I'm sure lessons have been learned. This was ultimately a training evolution for Active and Naval Reserve components of the MDSU Teams. But to believe that Navy personnel did not try their hardest or not care enough to take the proper precautions about a piece of Navy history is a little disingenuous. "The best-laid plans of mice and men often go awry."
To be completely fair, when considering the PBM's large & unique design, condition after decades of tampering, attitude of the wreck site and Time!, I think it was overly optimistic to believe that it would've be recovered and righted unscathed. Also it would be equally unrealistic not to expect that when the PBM initially set down on the lake bed upside down, with all the aircraft's weight and pressure on the higher and less robust empennage, there would not be some structural damage.
That being the case, like Glacier Girl, hopefully the smaller and sturdier single engine aircraft of the Lexington will withstand the recovery better. The real challenge will be the depth and pressure. 2 miles is a long way down. That's a long distance to coordinate a recovery remotely. Not to mention the weight of 2 miles of cable must be tremendous. At that pressure float bags may be problematic, especially with O2. Perhaps with oil or diesel, but i'm not sure Mr Allen and others would allow that due to the environmental impact should things go "awry".
Regardless, it will take a severe amount of mechanical engineering and planning to come up with a positive solution that will result in recovered and further undamaged aircraft for display. Personally I'd like to see them preserved and displayed as found. As well I'd like to see Lady Lex's stern plate and bell recovered.
Best of Luck and l look forward to further news.
