It makes all these other 'sad' "world record" endeavours seem pathetic doesn't it:
round the world via the poles
solo to the pole
fastest around world
etc etc.
Taking all the technicalities into account, it must have required an enormous amount of meticulous planning with little or no room for error. This is truly exploring the outer limits of the flight envelope (possibly even beyond - dare I say it), to the extreme.
A fantastic feat - one to perhaps match the 1972 world altitude record.
