Is this a threat, yes, are most of the videos showing the damage true, no. I think the drone being sucked into an engine of a jet would do as much or more damage to the plane. Drones have payload problems, the math of how much a drone can carry vs how long it can fly , or at what speed are the factors that make a drone such a problem as a attack threat. Still watch what this guy has been doing, he is doing his surveillance prior to the attack, which makes his planning something to think about.
