Error nearly caused a midair collision between Vistara A320 and Ethiopian 787 at Delhi airport in Nov 2023.

The high workload of an air traffic controller at Delhi airport resulted in two traffic collision avoidance system (TCAS) alerts between an Airbus A320 of Vistara Airlines and a Boeing 787-8 of Ethiopian Airways.

The serious incident occurred on 10 November 2023 in the late morning, as the A320 (VT-TQL) approached runway 29L, and the 787 (ET-ATL) prepared to depart on the parallel runway 29R, according to the Indian Aircraft Accident Investigation Bureau’s (AAIB’s) final report into the incident.
