Their journey of 22,422 nautical miles (36,084km)
Err, no. That’s the conversion for statute miles.
41525.544 km for nautical.
As Chris Miller of this parish points out in the comments over there:
The kilometre was originally defined as 1/10,000th the distance from the pole to the equator (and, despite some improvement in modern measurement and a change in the definition of the standard, it remains a very good approximation). So any circuit that includes both poles should be at least 40,000 km in length. How then, have they managed to find a route some 10% shorter (36,084km)?
A nautical mile was defined as a minute of longitude at the equator, so (again ignoring minor corrections for the oblateness of the earth) the journey cannot be less than 21,600 nm, which indeed it is not.
Aha! Has someone used a conversion from statute miles to kilometres, instead of from nautical miles? Yes, it would appear they have. Subs: report for your beating!
That one of the Times’ subs is an occasional reader here just makes it all the better…..
