Very sad about this...it's difficult for the moment to have reliable information, but from the french TV France 2 and for what it's worth, the plane was only undergoing a a painting job at Perpignan (putting I suppose the Air New Zealand colours on it) and not an overhaul visit...They say that it was taking off for a ferry flight back to New Zealand...The only reliable source would be the controllers at the tower, I shall try to get information...
