When dragons aren't readily available, you get yourself a couple of "drone killers." According to Entertainment Weekly, HBO utilized these devices during the filming of Game of Thrones' eighth and final season in order to prevent spoilers from reaching the public via drone footage taken from above the European sets.
“If a drone flies above sets, there’s a thing that can kill the drones, which is really cool. It creates a field around it and the drones just drop. It’s very X-Men.”
Shaped like a gun, a "drone killer" is aimed at any flying nuisance and shoots out a beam, disabling the drone and driving it back down to the ground. IXI Technology in Yorba Linda, California (fun fact: hometown of Richard Nixon), is responsible for the technology, which costs about $30,000 a pop. The company's also supplied new gadgets to the U.S. military for over three decades.
"The purpose is primarily for emergency situations," Oceanside police leiutenant Aaron Doyle told the Los Angeles Times. "It won't be used when someone complains about a neighbor flying a drone. It's pretty much for a life-or-death situation, to save lives."
For added precaution, HBO also turned the Game of Thrones sets in Northern Ireland into no-fly zones, forbidding any helicopters or planes to pass over the areas where shooting was taking place, wrote EW.
Season 8 of the high fantasy series is set to air in 2019, but we're curious, does the drone killer work against White Walker zombie drones?
