Can't offer any comment about the APU or whatever but in the 6 second video of the evacuation on le Figaro site I spotted at least three sizeable bags and lots of coats etc. coming down the slide.
Maybe we should start a sweep on such things!
On a more serious note, is there any point in the comprehensive cabin briefings that the likes of AFR do? It's pretty clear that many people don't pay them much heed.
