Not withstanding the obvious perils of flying drones/model aircraft in the proximity of airfields has there been any concrete evidence that Gatwick was disrupted by actual drones. At the time I wondered at the lack of pictorial evidence given today’s culture of using mobile phone to record just about everything.
I read a report somewhere in one of the flying magazine that there was some doubt as to what caused the Gatwick incident.
As for the CAA they certainly don’t do themselves any favors.
