Was there not indication of a fire at the first officer windshield heating element connection? I can't remember now the places where I saw that mentioned and how that was identified - ACARS? Then the lavatory and equipment bay heat and smoke. A short at the windshield should have been protected by its circuit breaker but that is where I first saw someone suspect the first officer had placed their iPad near there. I don't know the design of the location, if there is some place to place an iPad, but most airplane knowledgeable people talked about a cockpit fire. I do remember that within minutes of the incident Trump Tweeted "There the Islamists go taking down another one." That is about as far as I read certifying it was an act of terrorism.
