Rami Igra, former head of the Mossad MIA Unit, draws a striking comparison between the FlyDubai cockpit attack and the lessons of 9/11. Speaking exclusively to NDTV, he says the incident highlights a new aviation-security challenge: what happens when the threat is not a passenger, but someone inside the cockpit? Igra also discusses the unidentified Omani co-pilot, possible radicalisation, the question of whether he acted alone and the potential for copycat attacks.
