Another Forumite Rendezvous at CFM is definitely mandated before the collection goes north. That'll be at least two, maybe three, years.
Doug sold the entire collection (less the FW-190D) to the Seattle Museum of Flight. Contrary to rumor, Paul Allen has nothing to do with it; SMF is separate though it has ties with Boeing. Allen has his own aviation collection in addition to 7 or 8 other museums.
