Good point Elizabeth. Of course, where we all struggle is less with the logic and more with the truth. Out of the hundreds of premises, mine included, most are false. Therefore, divining motivations and stimulation from the beginning of the tragic event to the end is frustrating. Similarly working backward in time from discovery to the initial cause hasn't worked to everyone's satisfaction. If the generally accepted explanations, transient phenomena such as wind and weather and the attendant ground effects has logic and the ring of truth. The mystery will never be definitively solved because transient phenomena are just that, transient. What are your thoughts?
