The switch that saved a Moon mission from disaster (bbc.com)

> CBS switched to a studio where two actors dressed in spacesuits simulate the Moonwalk.

> NBC, meanwhile, commissioned puppeteer Bil Baird to build astronaut marionettes. Baird (who would train Muppet creator Jim Henson) operated the puppets from an overhead gantry above a simulated lunar landscape

I can't find video of this, but I'd love to see it.
