The FO on my last trip told me that he went with his late father (began at TWA as a Connie FE) to repossess aircraft (DC-9s, 727s, 707s) from various countries, such as some in Africa and even from mainland China.
I told him about this thread and he knows how easy it is to remove aircraft from Africa, especially with a very experienced mechanic/Flight Engineer and lot of spare parts.
