There are elevators to get to the main areas. But, much of the things to see require walking. If you dig airplanes, go anyway. The flight deck is like an air show.
An electric chair I believe so, but bringing a electric scooter no because there's tons of crooks and nanies and lots of stairs and just common sense to not bring a scooter on the monument.
I don't know for sure, but there are a lot narrow stairs on board. You also need to climb stairs to get on board.
Yes. I believe they are ADA compliant and have elevators as well. I would confirm with them, however.
