It was likely the CAF's B-24A, as it has been based at the Cavanaugh Flight Museum facilities for a while now, under a partnership between the B-29/B-24 Squadron of the CAF, and the Cavanaugh Flight Museum. (Once the B-29A FIFI is made flyable again, it too will be based with the CFM, under the ownership of the CAF).
The only other B-24 that is flying, is the Collings Foundation B-24J, and I don't think it is down that way, as I seem to recall it has been up around New England more recently.
(Note: The CAF's B-24A, was originally produced as a B-24A (one of the very first of any B-24's in production) and was modified to C-87 status before going into service. The interior still shows the aircraft as being a B-24A in locations, and it was converted, to the best of Gary Austin's abilities (the then head crew chief on the aircraft) back to B-24A configuration. However, the nose is still a later D-model nose, added during the war I believe, or immediately post-war, and the cargo door is still in place.)
A third B-24, that could be made to fly, is Kermit Weeks', but it would require thorough maintenance - possibly a restoration. The aircraft however is extremely complete, much more so than most warbirds, featuring all of its original WWII equipment, having never been removed from the aircraft since production.
