 "summary": "A pilot reported an unidentified drone-like object near Delhi’s Indira Gandhi International Airport on 20 August 2017. Contemporary newspaper accounts describe precautionary restrictions and diversions, including an Air India account of two of its own flights diverting. A later government answer in Parliament contradicts the reports of an airport-wide stoppage: it says only one runway was suspended while operations continued on the others. These are different accounts of the restriction’s scope. The dossier preserves the disagreement instead of converting the newspaper duration or the ministry’s reply into an undisputed account of the whole airport.",
