We built the control
panel. It is small enough that it will fit through the bottom hatch,
so we can put lot's of cool buttons on it later and reinstall it.
The kids also painted the interior of the two "inspection - access - storage"
areas in the floor. The two access covers are painted dark gray on
the top and the same color as the storage area on the bottom. They
picked red and yellow, which really adds some color when they are open.
