Plane? What plane?

According to this BBC report, a Boeing 727 went missing from an airport in Angola sometime last month, and has yet to be found. On the one hand, it underscores that Africa is really big, but I really wonder if there are as many places with infrastructure support for a 727 as the article implies. Since one of the reasons the (presumed-) kidnapped pilot was down there in the first place was to determine whether the plane was air-worthy, I wouldn’t be surprised if the thing has crashed in the middle of nowhere, to be found several decades hence when that chunk of the middle of nowhere is getting razed to put in a strip mall.
