A pilot reported an unidentified drone-like object near Delhi’s Indira Gandhi International Airport on 20 August 2017. Contemporary police, airline and air-traffic accounts describe precautionary flight restrictions and diversions; a later government answer disputes an airport-wide shutdown.

What would help verify this dossier

A primary source or verifiable evidence that clarifies whether the reported object was a drone. Evidence for another explanation is welcome too.

These are research questions based on the public dossier, not a checklist that guarantees confirmation. Editors review new sources and record any change as a new revision.

Drones involved

The cited sources do not name the type of drone.

What we know

Contemporary reports describe disrupted flights and diversions. A later parliamentary answer says only one runway was suspended while others continued operating. The exact extent and duration of the restrictions remain disputed.

Indian Express relays Delhi Police and AirAsia statements. The Times of India’s separate TNN report interviews an air-traffic official and Air India about disruption. AirAsia’s unidentified-object statement is shared, not independent drone identification. A later official parliamentary answer provides a conflicting account of the restriction’s extent.

What remains unknown

No technical drone identification or operator established. Reports variously give about 40 minutes and 46 minutes and refer to an earlier separate scare that day. No exact closure duration, airport-wide shutdown or observation clock adopted. The parliamentary answer dated19December2017 concerns20August but contradicts contemporary all-runway accounts.

Operator attribution: Not established. No operator established in the selected reporting.

How to read a dossier

Every incident is judged on three separate questions. An airport can be confirmed closed while it is still unclear whether a drone was involved at all.

Was there a drone?

Drone presence: reported by a source, confirmed by explicit evidence, inconclusive after investigation, or debunked.

ConfirmedReportedInconclusiveDebunked

What was the impact?

Closures, diversions, damage or injuries, with their own evidence state. “Not established” means no source reports an impact.

ConfirmedReportedNot established

Who is responsible?

Attribution is never inferred. A party’s claim, a charge and a court finding are shown as different things.
