Consider yourself lucky. I've been in Luanda recently and Lagos soon.
Good Luck, Arkie2. I was in Lagos for a 2-month TDY back in 1984. It was then the most dangerous spot on the planet and I don't think it's improved any over the years. Never been to Luanda, but a lot of my mates have and they tell me it was the absolute end of the earth. My old boss from Havana, Joe Sullivan, was the ambassador there.
Not being an aviation type, I can only surmise what might happen. How difficult would it be for a 727 to fly to Tripoli, undetected, fuel up, and then head for CONUS?
