Let me say something hideously unpopular ...
I was a doom monger about 558 getting airborne again but remain a doom monger about the sanity of restoring these precious airframes. There are too many times that 'last remaining flying example' becomes latest smashed example, all too often accompanied by the loss of the crew. We then have one less physical example for the next generation of aviators and engineers to inspect.
Let us hope that she operates safely until a timely retirement with all her frames and crew intact.
