Wasn't the evac off that Saudi L-1011 problematic as the doors wouldn't open due to the cabin not being depressurized after the landing?
Anyway that evac test video got a run recently on a 4-part 'mini-series' on the A380 development shown here in the Old Dart. It was 850- or 870-odd punters getting out in 78 secs with half the doors inop, in darkness. They also had beefy blokes at the bottom of the slides helping them off.
That said, that's at least a couple of hundred more than anyone has said they're going to carry (so far!!
)
