In a conversation to Sky News, Tingley said officers had found a damaged drone at the airport in Horley and were on an "expedited" effort to examine that drone for evidence.

There's an increased financial motivation to bring the perpetrators in, at least. Gatwick Airport is now offering a £50,000 reward (about $63,300 US) through Crimestoppers for useful information, and that's on top of the £10,000 (roughly $12,700) from Lord Ashcroft. Whether or not anyone bites is another matter. Drone flights like this are difficult to trace in part because operators can easily fly their machines from hundreds of feet away, and frequently more. There might not have been anyone who could see the pilot(s) in the first place, let alone identify them.
