There does appear to be quite some hysteria surrounding the baggage issue.
Firstly, apart from a couple of instances, in the published images the bags are small or laptop size. Secondly and this will ring true with any frequent airline traveler (as opposed to 'armchair experts'), there is no way that a group of passengers evacuating in an emergency are going to stand patiently while someone fumbles around in or indeed even attempts to open an overhead bin. The reality, as shown in all the reporting, is there were no problems. Flight crew, cabin crew and passengers all dealt with the emergency using training and common sense and walked away. The real issue is why the engine caused an uncontained explosion and fire. I guess we'll find out in about six months.
