Several others are undergoing rebuild, including in Canada.
Jerry Yeagen the owner of the one in the film put a lot of his collection up for sale recently citing he could no longer afford to do it anymore.. The B-17 and FW190 have already gone, the rest of the fliers were slated for sale too

The BAe one where the engine quit was down to a faulty assembled unit if I remember correctly, not negative G as the cause..
