@proactivepaul All 379 passengers and crew evacuated. Looks like the smaller CG plane took a full hit as the A350 was landing. So would have been a quick routine evacuation, thankfully, with minimal fuel load.
@proactivepaul When in doubt, ask the planespotters: https://www.airliners.net/forum/viewtopic.php?f=3&t=1490191&start=150
Some great (and bad) armchair analysis and footage collated here too. Looks like the A350 was already on the runway, and the CG plan had not seen the incoming plane and had moved from its hold point on the taxiway.
