My amateur theory is that there was some depressurization of some kind and the pilots desperately tried to adjust course but only did partially. The reason for the disappearance is probably mostly due to Malaysia's early lack of sharing critical information, so the plane went in a different direction than originally presumed and, when flying for 6 hours, ended up being a long way from where they thought it should be. As they say in the article, another plane, the Rio to Paris wreckage, took 2 years to locate and they knew exactly where that plane was.
