You may have hit the nail on the head to an extent. There’s nothing like creating a war to sell expensive arms. An expensive drone detection system costs millions, so let’s create our market.
I’ve been keeping up with the Gatwick drone story, and becoming convinced there was no drone. Since then several other airports, Heathrow in Jan 2019 have been closed by apparent drone activity. In the case of the Gatwick drone, it was reported that lights were seen. Drones use a gps system to send info to the user so can’t be flown into restricted airspace without hacking the software. If you’re hacking the software to secretly fly in restricted airspace then it would make sense to turn the lights off while you’re at it.
Here‘s the bit I read, but there is also a Guardian long read. They seem to be the only media who have asked any questions.
