You’d have to re-create the Saturn V. The plans were lost decades ago.
I think they’ve been using the same Vehicle Assembly Building for the shuttle that they used to use for the Saturn. Not to mention the colossal crawler.
Actually, I’d love to see them shut off the air conditioning for a day. An old book I read way back when sad if they ever did that the building would form it’s own clouds and rain.
Nah, HSV has the real deal.
