Decided to try out what Jefmajor did in one of his KSP Let's play Videos and make a long range Atmospheric plane and go to the north pole.
Cruisin' (Our pilot apparently hates flying)
Look at all that snow!
In addition, got some good speed going, most speed I've gotten for a purely atmospheric plane.
Comin' in for a far-north landing.
Pretty fun plane I have to say, has some issues, but what design in KSP doesn't?
Initially thought I'd have a lot more issues with the back mounted fuel tanks I used but they worked.
