C'mon guys, it's time for a reality check. A large number of investigators from a variety of organisations have independently examined the evidence and come to identical conclusions. We now have armchair experts using conspiracy theories to come up with entirely different conclusions and they are totally convinced that they are right. I suggest guys that you clear your mind of any prejudices and thoroughly read the interim report - it is an interesting read and comes with slides etc to make the visualisation of the events much easier. The "What" part of the question has been answered and is clear. We now wait for the final report which should tell us the answer to the "Why" part of the question. I'm certainly interested in what caused the oxygen bottle to split the way that it did.
