Thank you all...
I have made it to Djibouti in Africa.
I avoided Sudan by going via Jiddah in Saudi Arabia - cost me som 750 US dollars to land there though.
One reason for flyiing via Djibouti is, that a "N" registret plane is not allowed to fly into Ethiopia north of the 12 degrees North latitude.
I use a guy in Denmark fot getting flight permits. His name is Bo Therkildsen.
