I know next to nothing about drones nor aircraft -- and now I'll probably prove it.
It seems to me that if an airplane can suck in a bird and be disabled, the same could be said for sucking a drone. And I'd hate to run over one that stalled and fell while I'm doing 200 and it's trying to get a real neat shot.
That said, I spent a day at SpeedWeek last year helping a documentary crew whose drone-driver and photographer were getting some sensational images.
