Lifting a waterlogged plane is a mite delicate. I note WCBS-TV says they have load cells in the lift rig - they lift a foot or two, let that much water drain, then lift a bit more, always keeping the lift forces under control. Lifting too fast will cause the structure to break up, and then they have to start over - this time lifting the separated bits.
Boeing sent their recovery crew to the B-307 ditching (several years ago) in Puget Sound to validate their recovery procedures - and the priceless 307 was then restored (again!) and flown to IAD to the NASM annex there.
