Circumnavigation on Kerbin-Rescaled to 2.5

Taking a break from debugging, I was wondering about something fun to do on this Sunday. 

So. that's the deal: do a leisure Kerbin circumnavigation journey using a hypersonic craft for 6 rich and bored tourists with more money than common sense.  To make things more interesting, the circumnavigation  will be made from pole to pole instead of following the Equator.

Problem: doing it on Stock Kerbin is terribly easy.

Solution: 2.5x Scaled Kerbin. :)

This is Marco Polo Mark 2, for 6 tourists and one pilot to travel at 30K meters high and ~Mach 5. Built using Stock parts, TweakScale (on wings, wheels and control surfaces only).
