They are expensive to fly for sure! But I would sure love to take that ride! They are comparing notes, so I bet a copy of Papa's flight manual is on Doc too! I know that would make him happy!
The B-17 was $600 a half hour flight, so the B-29 is likely $2000 for the same flight time. But it would be worth it!
