Hi there,
If it was a BA 747-400 in French airspace enroute to Johannesburg would it not be closer to FL330 as it would need to burn of a few thousand Kgs of fuel before climbing to a higher level?
And it would have been an evening flight, normal departure time is either 7pm or 9pm local (or there abouts)
I wonder if anyone on board even realised anything out of the ordinary had happened?
Cheers Ant
