About 45% of the passengers overall took their hand luggage with them (observably about 95% plus of the women pax took their personal handbags) and about 70% of women pax wearing high heels refused pointblank to remove them in the end the cabin crew simply gave up and concentrated on getting everyone out ASAP.
These days I'm sure pax will stuff ipads down their trousers/bras first then evacuate.
