The framing collapses a parked-vehicle-on-a-taxiway report and a barely-avoided collision into one scary count, so the felt risk of being on a flight that nearly hits something tracks the headline rather than the severity split. No published survey isolates fear of a runway incursion specifically; it folds into general fear of flying.",

Per-flight native uses the same FY2024 serious rate over 2 operations: ~3.1e-7 x 2 ~= 1 in 1.6M, rounded conservatively to 1 in 2.4M to reflect that not every serious incursion involves the passenger jet (some parties are general-aviation aircraft, vehicles, or pedestrians).

Approximately 60 percent of those incursions were attributable to pilot deviations, approximately 20 percent were caused by air traffic controller action or inaction, and the remaining approximately 20 percent were caused by vehicle or pedestrian deviations. It's important to note that the total number of Category A and B runway incursions was 23. Although these statistics suggest that runway incursions account for approximately 0.003 percent of all NAS operations, and the more serious incursions in Categories A and B combined account for about 0.00004 percent of all NAS operations, we recognize that any number is an unacceptable safety risk and we are working hard to drive the number of such incursions to zero.",

  "caveats": "This counts the near-miss event, not a collision and not a death. Actual injuries or fatalities from US runway incursions are far rarer than the incursion rate itself — most Category A/B events end with separation restored and no contact. The headline rests on a chain of assumptions (per-operation serious rate, two operations per flight, attribution of a multi-party event to your specific aircraft) and on a denominator (~58.6M FY2024 operations) partly derived from a 30-per-million rate that appeared only in search summaries; the per-operation serious rate is anchored instead on the FAA's confirmed FY2023 figure (23 of 54.4M) and the OIG's confirmed FY2024 count (nine serious). Year-to-year variation is large: FY2023 had 22-23 serious incursions, FY2024 had nine, so the lifetime figure could plausibly double if a high year recurs — hence the wide 2e-5 to 2e-4 band. No survey isolates fear of runway incursions, so perceived.kind is intuition. personal_factor_multipliers are omitted: the strongest available differentiator (busy-hub vs low-traffic airport) lacks a named source giving a >=2x per-passenger effect, and the only quantified trend (\"15 percent higher than a decade ago\") is below the 2x inclusion threshold. 8D self-score average 4.375, all dimensions >=4; clears thresholds.",
