The first hanger houses a number of the aircraft. There is a catwalk on the north side of the room that gives you an overall view of the room and allows you to get a closeup of the aircraft that are suspended from the ceiling. Though this is an impressive sight, there's nothing like getting on the ground floor and walking among the planes. There is plenty of space between the planes, and because of the size of the area, it does not seem crowded with visitors even though many people might be there at one time. I guess enormous is the best word to describe this hanger.
