The nice cut out walk way for the museum tourists like me was made possible by removing a section of the wing spar. The B-29 at the Air Force Museum at Wright Pat. The round thing above is the pressurized crawl space for the crew.
These guys started at the mountain top and just went downhill. You would need 2 trucks for that. They had just ridden through the 3 mile long tunnel in the dark (with bike headlights)!
Ran out of water? No worries! Water is safe to drink from and tasted better than bottled water:)
Dark wet and cold, but probably warmer in the winter time compared to the outside
