When i was watching Kate blab out her whole sob story to Jack, i knew that their was more to the model airplane than she let on.
This is my theory: Kate for some reason was mad at her boyfriend and sabatoged the plane he was on. Only then she got caught for the robbery and got shipped onto the plane that she sabatoged. She and her boyfriend went down in the crash and now she blames herself for his death in the crash.
