Did it happen ?
I'm just wondering if you flew this in the end ? If so, what route did you go ? I'm thinking of something similar. A rough, course grain, view on SkyDemon suggests (roughly):
4h to North coast of Spain
4h to South coast of Spain
4h to Morocco.
So that's 6 days in total, 2 pilots with stopovers should be able to do it.
My main worry:
1. French AIS / RT
2. Spanish AIS / RT
3. Working out if I can leave from one airfield to another country
