 "evidenceNote": "Each dossier separates three claims: drone presence, impact and attribution, each with its own evidence state and supporting sources. 'reported' means a source describes the claim without sufficient identification evidence; claims by parties to a conflict are never 'confirmed' on their own. Counts reflect dossiers in this curated archive, not all incidents worldwide. windowStart/windowEnd are reporting-window calendar bounds, not individual event days; legacy date remains the compatibility/sorting date for such records.",
 "locationNote": "lat/lon are the dossier's own approximate coordinates (see locationPrecision) and are empty when the incident location is unknown. referencePoint {lat, lon, level, name} is a display reference only: a fixed point in the named city (GeoNames), region (its administrative seat), sea or country (Natural Earth label point), derived at build time. It is not a geolocation, not an estimate of the incident location and may change when the dossier's place becomes more precise: reference point; incident location unknown.",
 "detailsNote": "media, followUp and archiveEntity are editorial, source-indexed additions. operationalEffects may also contain AI-assisted source-checked additions identified by autoEnrichments, with the dossier remaining review=auto. autoEnrichments preserves the literal quote, speaker, source publication cutoff and check provenance; a quote match is not editorial review or independent confirmation. Media is publisher-link only, has its own evidence status and never establishes drone presence or attribution. Debunked original-media links are removed; archived revisions omit media references. archivePattern is computed from mapped published event records at generated time, not a worldwide incident count. Null asOf means not established; publication time is not substituted.",

  "summary": "Reported drone sightings disrupted Gatwick Airport between 19 and 21 December 2018, causing extensive cancellations and passenger disruption. The operational impact is well documented; the aircraft type, operator and intent are not established in the selected public evidence. A later police account explained the investigation’s limits without resolving those questions.",
  "impact": "Hundreds of flights were cancelled between 19 and 21 December 2018.",
  "evidence": "Reuters’ contemporary airport reporting describes the disruption and the return toward normal operations. The Sussex Police and Crime Commissioner’s minutes of 18 October 2019 record the chief constable’s account of witness evidence, police inquiries and the scale of disruption. The minutes distinguish sighting reports, witnesses and investigated people: none of those totals is a count of separate drones. Police described credible witness evidence of incursions, but the selected public record does not supply technical identification of an operator or aircraft model. The Home Office’s later policy discussion reuses the incident as an example; it is not an independent accident investigation.",
  "unknown": "The October 2019 account said realistic lines of inquiry had been exhausted while allowing reassessment if new information emerged. That is a dated investigation position, not proof that the sightings were fabricated or that a culprit was identified. The Reuters article’s publication date must not be used to infer later legal outcomes absent from its text. The dossier does not reproduce private suspects’ identities or precise flight positions. Large passenger and flight totals describe operational consequences, not proof of a particular drone type.",
