In the seconds between recognizing danger and acting upon it, an Amazon cargo jet ran off a Miami runway — a gap measured not in negligence but in the irreducible time it takes for human decision and mechanical response to converge. The National Transportation Safety Board has reconstructed that sequence with precision, finding that the pilots moved correctly but not quite soon enough, constrained by the physics of a large aircraft and the procedural realities of emergency flight. Their findings remind us that aviation disasters often live not in failure of character, but in the narrow margins
