A little light
1.2kg is on the low side of drone weights these days. A larger drone carrying a real camera is going to weigh more and hit harder.
It's not just about an engine being able to survive ingesting a drone or the windshield ONLY getting a nick in it. When I happens, it means that the aircraft needs to be pulled out of service and inspected to be sure there hasn't been any damage that requires repair. For an engine, that can be a major task. If the aircraft was scheduled to be turned around in an hour to travel to the next city, there could be a few hundred people that will be scrambling to find another flight or a hotel room and missing any intended connections. That's tens of thousand of Pounds in costs from one little shite playing in traffic.
