It may be of interest to some, to know that Liberty Belle had a very unique post-war history,
Pratt and Whitney used it as an engine testbed with a fifth, (usually turboprop,) mount on the nose.
She was retired to the New England Air Museum in Connecticut, but was 'destroyed' by a direct hit by a major tornado.
Amazing restoration efforts turned her back into a B-17G, reg: N-390TH.
