Some vintage aircraft are visiting Lawrence today, including a restored B-17G Flying Fortress and a restored B-24J Liberator. I took my older son Nicholas to see the planes today, and the $12 "get inside the plane" tour was worth every penny. You could also purchase a ticket to actually fly in the plane, but that was a bit out of our price range. Maybe someday...it would certainly be a peak experience.
I asked Nicholas (age 11) which aircraft he would rather have flown in combat. He said "the B-17" and explained that it looked sleeker and more durable than the B-24. Interestingly, this is what most World War II bomber pilots felt at the time.
