340 NM total round trip and not counting time on the ground. In the book in question, the Harrier drops it's passenger off within 10 to 20 Miles of the Norwegian / Soviet border on a cold arctic night so hot and high isn't an issue, plus the only bits of the mission that are VL / VTO are in the middle of the sortie with tanker support either side (its just that the tanker has to be a lot closer to the drop off point than Thomas states in the novel). As most posts on here have stated, there are better ways of getting a large force on the ground, but the point of the Harrier in this matter is getting one or two people on the ground (and maybe back out) much in the same way as the RAF supported SOE with Lysanders in WWII.
