Also bear on mind that Gatwick Airport is infested with 30 or 40 amateur planefag photographers on a daily basis who take pictures of aircraft taking off and departing on a daily basis. These nerds have some very expensive zoom gear to do their work, and we haven't heard a peep from them either
It would be worth digging their social media circles to see what comes up. I'm sure they would've snapped a drone if they saw one.
