The quoted piece above comes from
AvCom topic - emergency in JHB now?
The 'authoritative' postings from people who are clearly clueless would suggest it is somebody trying to impress that he has inside knowledge when in reality he hasn't. Gems such as 'Thrust reverser warning light' (no such thing on a B744) with another idiot explaining that a B744 can only dump fuel from the centre tank (it can dump fuel from all tanks).
I do also know the pilots didn't 'refuse to fly it back'.
