A B-17 comes to my area from time to time. Next time it's here I'll gladly pay their fee/donation to help keep these classics aloft.
The Collings foundation flies various aircraft around the country. They've flown a B-17, B-24, B-25, Corsair, and P-51 to Ft. Lauderdale at various time. The best was when my father-in-law gave us a walk around of the Corsair, which he flew as a Marine Pilot.
