The discovery happened a while ago and divers surveyed the wreck. The difficulty is funding and obviously raising a fragile one of a kind bomber and preserving it. It's been in salt water all this time so dealing with all the problems that creates is a major issue.
The RAF museum is heading up the recovery and preservation. There was much talk of this bird last year but logistics couldn't be figured out fast enough to act then. So they needed to wait for the weather to change and start again this spring.
