First, commercial airline accidents involving deaths are by definition extremely unusual events. So the precise chain of causation and the specific contributing factors are typically different in each case. Moreover, it is often the case that the accident investigation team is left with choosing between different theories each of which is not likely. This is the reason the accident report reads probable cause and not 100% guaranteed cause. Sometimes it obvious what happened. At other times the facts are such that reasonable minds can differ on the actual cause of the accident. BA38 is one such example. At the end of the day the official cause is the official cause and the burden is on the nay-sayers to prove others, a burden they so far have been unable to carry in regards to BA38.
Second, please stop bashing the passengers with the luggage. While it is obvious to arm-chair analysts that this is not proper behavior in the aftermath of an accident people do not always behave in logical ways. Besides, the luggage could have been something that fell from the overhead bin and the passengers picked it up and took it off the plane because it was blocking the aisle. The cabin crew has enough to do in an accident without fighting with the passengers over carry-on luggage. The fact is that the only two people who died (so far) were ejected so that means the cabin crew did their job well under intense stress.
