@RedHaus This is what the police statement says about the imaging ...
Polair conducted initial searching, including using infrared FLIR, out to a distance of 12km from the homestead while a drone captured images of a 2.5km radius from the homestead, a 2km radius around the dams and two known travel routes for 8km and 6km from the homestead.
In addition, an aircraft fitted with highly specialised camera equipment captured images on two separate occasions –the first to a 10km radius from the homestead and the second to a 15km radius from the homestead. The total area covered amounts to 706 sq/km.
This imagery has been processed using specifically designed, specialised AI software programs and reviewed by Task Force Horizon investigators.
