Re: Pink Unicorn?
Fact: UFO reports are down by pilots.
So are bird reports.
In fact at Heathrow (along with most other airports) there's a near linear relationship between the decrease in bird sightings and the increase in drone sightings.
Never mind that the airspace around airports is heavily surveilled and anything with weather radar looking for microbursts is going to see drones lit up like christmas trees thanks to both their metal content and the doppler effects of the rotors.
