Sussex Police have released the man and woman arrested on December 21st after determining that they're "no longer suspects" behind the multiple incidents. Don't anticipate new suspects in the future, either. Detective Chief Superintendent Jason Tingley said his force continued to "actively follow lines of investigation," but didn't hint at where those might lead. 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.

The airport's only runway was reopened on Friday morning, with a range or protection and surveillance measures reportedly put in place to prevent further chaos. One of the key tools for spotting drones will be radar. "The military has a range of technologies to secure airspace against planes, helicopters and drones," Mr Gill said. "They will be able to provide military-grade radar technology in order to help detect the drones and potentially the operators." One such radar system that may be deployed at Gatwick is the Israeli-developed Drone Dome system, of which the British Army bought six earlier this year.
