Whatever the reason, heartfelt sympathy to everyone whose Christmas and holidays have been ruined by the problem. WTF where’s the fire glitter shirt. I can’t even imagine the frustration and disappointment of the travelers. Best wishes to each and every one of them. Gutted for you. Even the most advanced drones available to the public have a max flight time of around 30mins. I mean, the thing keeps landing and re-appearing, presumably to charge its batteries. Next time it lands, follow it “home” with their own drone! It’ll lead you to the operator!
