Still can't get over that B-17 tour. It's a shame my batteries died before I could shoot everything, but it was a shock to me to see how light the frame was. This was towards the rear of the plane the thing under the yellow tank is where the bottom (waist?) gunner sat. The side-gunner's station is obvious, but those wires running fore-and-aft are the control cables! And the surface outside the ribs is a pretty thin aluminum-alloy skin.
Good picture. Equally impressive is how fast they built them, and how ineffective each one was compared to modern bombers. Imagine flights of hundreds of bombers today - totally unnecessary!
There is a local air museum that rents a B-17G for parties. But you must leave it on the ground. With special arrangements you can get in several of the planes.
