“Just because they’ve apparently got noisy whirring propellers”
Described as totally silent in the article. But seems like I did hear a report at the time of drone-like noise(?).
To get any appreciable range out of drones they must be large enough to carry a fuel source or an impressive battery bank which would make them large. Doubt these are all predator type drones or amazon delivery level drones flying way out in the country. A fuel driven drone would emit way more than a 'drone like' prop whir. Maybe musk got tired of playing with cars batteries and switched to drones.
