The best news is there is more than one being restored.
In the same hangar as the Belle is the sole surviving “Sharktail” early B-17…a D, a early-war combat veteran named The Swoose.

And about 30 miles from those two ships is the restoration effort of a private group of a B-17G currently called Champaign Lady.

And at the Mighty 8th museum located near Savannah ,Ga is this one.
