Space shuttles and horses' behinds

Post by Dreamweaver »

Here's what Snopes has to say about the topic- https://www.snopes.com/fact-check/railr ... -chariots/

It's a long story, but includes this
When we see a Space Shuttle sitting on its launch pad, there are two big booster rockets attached to the sides of the main fuel tank. These are solid rocket boosters, or SRBs. The SRBs are made by Thiokol at their factory in Utah. The engineers who designed the SRBs might have preferred to make them a bit fatter, but the SRBs had to be shipped by train from the factory to the launch site. The railroad line from the factory had to run through a tunnel in the mountains. The SRBs had to fit through that tunnel. The tunnel is slightly wider than the railroad track, and the railroad track is about as wide as two horses’ behinds. So, the major design feature of what is arguably the world’s most advanced transportation system was determined over two thousand years ago by the width of a Horse’s Ass!
I dream, therefore I am.
