I think that if it were a bomb, there would be a wide debris field, meaning you would see pieces of the plane in the ocean or jungle. But what is odd is that the pilots didn't issue a distress call. The weather was fine,so whatever it was,it took the pilots by surprise. Air France #447 plane that went down was caused by icing in pitot tubes. The Maylasian plane was a 777-200, the airframe was only 11.5 years old. The Boeing 777-200 has an excellent safety record. On Fox News,they are reporting a door from the plane has been spotted. I saw the pic,and it does look like a plane door. Also The plane was last inspected 10 days ago and found to be in proper condition. I thought about pilot error being the cause of the crash,but if that's the case,why no distress call? Also saw on a Chinese news site,a video of a man calling his family member,(who was a passanger) cell phone. Instead of going to voice mail, the passengers phone rang and and I guess disconnected. That's weird too. Whatever happened,it was a sudden and catastrophic event,and possibly a criminal act.
