The National Air Museum at Geneseo lost their lease on the airfield several years ago (I think it was '99) and relocated to Elmira. They have since, AFAIK, closed their doors. Their B-17 "Fuddy Duddy" is on-loan to (again, I think, going from memory after getting home from work here) The Collings Foundation.
BTW, Dr. Bill Anderson crashed the P-40E he had based at Geneseo a while back as well and sold the wreckage. I don't know the specifics, but I heard a rumor thats its been repaired and is back in the air.
There has been talk several times over the years of starting a new museum at the Genseo Airfield and having the "Wings of Eagles" airshow return there, but the rumors never amount to anything.
