They have not only the actual Wright Brothers Cycle Shop building and their house from 7 Hawthorn St. Dayton (Ford moved the buildings), but Ford hired their mechanic Charlie Taylor to set everything up as it was in Dayton. Taylor re-acquired the original tools; not the same kind, the exact serial numbers. When you walk outside, there's even a Dayton manhole cover on the ground.
For those that aren’t aware, one of the locations is on the Capitol Mall in Washington, DC and the other - the Steven F. Udvar-Hazy Center - is near the Dulles Airport in Dulles, VA.
The latter has the Space Shuttle Discovery, a Lockheed SR-71 Blackbird, a Concorde… and the Enola Gay.
The downtown location has more interpretation of artifacts - sometimes at the Udvar Hazy it's hard to really appreciate what you're looking at without a docent-led tour or other context.
It also doesn't hurt that the docents include people like an SR-71 pilot.
Oh, that’s great news!
