there are two things not mentioned in the webpage Chuck showed us:
1)the macchi was grounded after a bad accident caused by the pilot while taxiing.
2)the recovered and fixed plane is not the one in the Museo della Scienza e della Tecnica, but it's in the Aermacchi building in the main entrance gate.
A sad story indeed, the Aermacchi said "the fuselage is too badly damaged to be restored to flying conditions again", but this being said by a specialized aircraft factory who has original drawings is at least ridiculous.. they realised that flying her was starting to cost too much..
A Macchi 205 would be great, but I'd be happy with a G.55 as well, maybe the G.59 fuselage in Duxford might receive such conversion
