Two categories of hardware are expected to reach the ground: • Tungsten components -- denser than lead, they shed heat slowly enough to land intact • Mirror parts from Swift's X-ray telescope -- fused metal structures that resist ablation NASA says surviving pieces will most likely hit ocean (roughly 70% probability), with a small chance of landing in Africa, South or Southeast Asia, Australia or Central/South America.

Everything outside that equatorial band is safe. The uncertain re-entry window means the zone spans thousands of kilometres along the track -- the exact impact corridor will only be known once debris is confirmed.
