Pixhawk 248 Firmware -

Mara had set a grid search for an eroded coastline. The drone should have followed the plan, line by line. Instead the aircraft angled, curved gently as if following a trail only it could see. It paused over an abandoned lighthouse, banked, then drifted inland following an old animal path that cut across fields and through a stand of pines. The camera’s footage showed the terrain the grid would have missed: a subsidence hidden by dunes, a patch of invasive plants starting to choke a salt marsh, three cairns stacked in a row—markers? Or someone’s memorial?
