Drone-like object report disrupts Delhi airport operations
Current state
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.

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.
Claims
3 sources · 3 original statements. Sources that repeat the same statement count once.
| Claim and source passage | Original source | Assessment |
|---|---|---|
| AirAsia described an unidentified object rather than establishing drone identity. “spotted unidentified object flying close to aircraft” [1] | AirAsia via Indian Express (relayed) | supports: Short literal passage read on public source page; original evidence origins are distinguished in evidence. |
| Contemporary police account describes precautionary restrictions. “operations at all the three runways were closed as a precautionary measure” [1] | Delhi Police via Indian Express (relayed) | supports: Short literal passage read on public source page; original evidence origins are distinguished in evidence. |
| Air India separately reported diverted services. “Two of our flights to Delhi, including one on a wide body, had to be diverted.” [2] | Air India via Times of India (relayed) | supports: Short literal passage read on public source page; original evidence origins are distinguished in evidence. |
