Not to come across as sounding negative.....load it on a Freighter and fly it to Europe that way.
Probably a lot cheaper In the long run and if you were to have maintenance issues enroute while flying the machine itself.....it could be really expensive.
But if you were to fly the machine I would think going west and north would be the better routing.
You ask 212man....he has done some ferry flights from Europe to Nigeria in the past.
