I was talking to work colleagues about this and mentioned that it's crazy that people thought it was a good idea to grab their bags first. If I'm shouted at to evacuate I'm running for it, especially if smoke is coming into the cabin. My colleague's response was "Yeah suppose, but if your passport is in your bag then getting home will be a pain in the arse"... glad to hear people think that far ahead about themselves rather than ensuring as many people can get off as quickly as possible...
im surprised the cabin crew let them down the slides, if the baggage punctured the inflatable escape route then there would be big trouble.
