Has today resurfaced in The Guardian. Apparently, a Canadian pilot named Bob Strother recognised it in Conakry under a new Guinean registration (3X-GOM), where it is supposedly being used by local business interests. (Guardian report) According to the paper, "an American official in the region said this was the first he had heard of the plane since its disappearance from Angola's capital, Luanda, on May 25. People have been looking for this thing everywhere," the official said. "We've had reports that it crashed, that it was in South Africa or Nigeria, but nothing for sure, not like what you've just told me."
But a "Western official" in Sierra Leone was closer to the story...
"A western diplomat in Freetown, Sierra Leone's capital, said it was more likely the plane had simply been snatched from Luanda be cause its owner was reluctant to pay year-long airport taxes, totalling around £30,000.
"There's always a shady side to business around here," he said. "But as for the terrorism stuff, that sounds like a complete load of rubbish."
Maybe he rants too.
