I was following this link from Boing Boing the other day, to a really cool YouTube movie of a large R/C scale model of a Lockheed Constellation, and started browsing the other movies put up by the same folks. All props to the Constellation model, but what you’ll see embedded below is even cooler: a scale R/C model of a B-29 Superfortress, and the experimental Bell X-1 plane that first broke the sound barrier with Chuck Yeager at the stick. This knocked my socks off!
