Funny how rumours go.... I heard this rumour:
That TAAG was in negotiations with a Portuguese based airline, Euro Atlantic Airways, to operate those same B777's.
As TAAG have been banned from flying the EU this company would operate the aircraft for them beteween Luanda and Lisbon as they have a European AOC. Crews would be a mix of TAAG staff and a some Portuguese from Euro Atlantic.
But that would mean that the Angolans would have to get a JAA license, dunno if that would workout....
