I had heard that the 4 feet, 8.5 inches was the average distance between
a distressed damsel's neck and ankles.

The US standard railroad gauge (distance between the rails)
is 4 feet, 8.5 inches. That's an exceedingly odd number.
Why was that gauge used?
Because that's the way they built them in England, and
English expatriates built the US Railroads.
Why did the English build them like that?
Because the first rail lines were built by the same people
who built the pre-railroad tramways, and that's the gauge they used.
Why did "they" use that gauge then?
Because the people who built the tramways used the same jigs and tools
that they used for building wagons, which used that wheel spacing.
Okay! Why did the wagons have that particular odd wheel spacing?
Well, if they tried to use any other spacing, the wagon wheels would
break on some of the old, long distance roads in England, because that's
the spacing of the wheel ruts.
So who built those old rutted roads?
Imperial Rome built the first long distance roads in Europe (and
England) for their legions. The roads have been used ever since.
And the ruts in the roads?
Roman war chariots formed the initial ruts, which everyone else had to
match for fear of destroying their wagon wheels. Since the chariots were
made for Imperial Rome, they were all alike in the matter of wheel
spacing.
The United States standard railroad gauge of 4 feet, 8.5 inches is
derived from the original specifications for an Imperial Roman war
chariot. And bureaucracies live forever.
So the next time you are handed a spec and told we have always done it
that way and wonder what horse's ass came up with that, you may be
exactly right, because the Imperial Roman war chariots were made just
wide enough to accommodate the back ends of two war horses.
Now the twist to the story...
When you 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 would 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 happens 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, as you
now know, is about as wide as two horses' behinds.
So, a major Space Shuttle 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.
And you thought being a horse's ass wasn't important. Bernie
