Rep. Adam Schiff, D-Calif., member of House intelligence committee, on missing EgyptAir plane: 'We are scouring our intelligence resources to see if we can aid in the determination of what happened to the plane. If terrorism was indeed the cause, it would reveal a whole new level of vulnerability to aircraft - not only from those flights originating in the Middle East, but to those departing from the heart of Europe and with, at least in theory, far better airport defenses' - NBC News
