see a different kind of action or reaction. now you have the transponders going down and akars system going down and this turn for no reason. if the pilot because they had an explosive depression, they have already programmed the track to go through kuala lumpur to beijing so the airplane would have continued to fly towards beijing. it would not have been programmed to make a left turn and come back. if you had an electrical failure, there s a backup, where you could still get generator power to run critical instruments. absolutely but you have to come down to a lower altitude. it powers air conditioning electrical, everything on the ground is functional in the air, but you have to be at the lower altitude. that further muddyes the water of exactly how far this could have gotten and how expanding this radius is. we ve seen a broader and broader area being searched. a lot of questions and way less answers than we d like. thank you as i said to lester
