I was at WrightPat mueseum two weeks ago; under a B-2, and that was a weird experience.
The really dark grey of it’s finish, coupled with the black interior of the hanger and low lighting gave it a VERY powerful ‘presence’, just sitting there.
But; how do you get into a B-2? Climb a ladder and walk across the wing to the cockpit?
Nope, there's a hatch under the left side by the nose landing gear with a retractable ladder attached.
