Interesting part of that is the “drone alert system”.
So do they have Aeroscope (in which case finding the operator is likely easy) or a 3rd party product?
Or is it just someone going “i think i see a drone…”.
Probably a pigeon with an Apple AirTag attached to it. 
Hi jockyb ye true 
According to American news reports it was a weapon of Mass Destruction manufactured somewhere in a cave in Scotland 
We were filming a wedding at Carlowrie Castle on Thursday, which borders Edinburgh airport. One of the staff told us that a recent guest put his drone up in the grounds, within minutes armed police were on the scene.
So is this aircraft still waiting on the runway at Edinburgh Airport whilst the police chase their own tails around (Plane delayed as police hunt pilot) 
@Drumsagard Did you have to get ATC approval John for Kirkliston?
@D0c.Col Yes Colin, all very easily done on their website. At other airports we have had to contact Police Scotland then get permission from ATC (they won’t consider requests without a Police incident number first), at Edinburgh they contact the Police for you, so saves time hanging on 101.
@Drumsagard Just wandered John as I liked the look of the castle and might visit later in year. I had to use the Police Incident number when getting permission from RAF Luchers when I flew in St Andrews. I thought it was a great idea TBHđź’ˇ
It is a great idea Colin, but a couple of times I’ve waited over 10 mins to get through to someone on 101, the first time I mentioned getting an incident number for a drone flight the operator didn’t know anything about it, then had me hanging on for ages. They are getting better though 
I must have been lucky then, got through morn of intended flight and after a couple of minutes the female officer wished me a happy flying day!
