A flydubai flight travelling from Dubai to Tel Aviv has turned into a terrifying high-altitude struggle when one of the pilots was attacked in the cockpit by his co-pilot. Passengers were fighting to help crew regain control of the plane as it plunged 17,000 feet before making an emergency landing in Saudi Arabia. Today, counterterrorism expert Greg Barton on what we know about this mid-air attack and what it could mean for security in the region. Featured:Greg Barton, Rector of Deakin University Lancaster University Indonesia.
