CNN opens the speculation cavalcade with this video on Germanwings flight 9525. Curiously, the airplane descended with a constant speed and angle (assuming the graphic depicting vertical profile is accurate). Commentator Chad Myers, a meteorologist, is right to conclude that it was not an uncontrolled descent. This brings to mind the possibility of controlled flight into terrain. It’s an ugly thought. Also: why did CNN use a meteorologist to talk about this?
