As far as I know, he has left both airlines and applied posts in the warzone/military base. And after searching the threads here, I know there are posts from those pilots working in UN but I have no idea how to link up with them for more information. As the UN would outsource the contracts of pilots to other agencies for recruiting so the terms and conditions would be a bit different I guess, and his contract would be around two to three years.
Hope if there are any pilots working for the UN that could provide more information. Thank you very much.
