According to sources, the incident occurred on Wednesday at around 7 pm when the Indore Air Traffic Control cleared SpiceJet's Delhi-Indore flight for landing. Around the same time, the airline's Indore-bound flight SG 1053 from Hyderabad was also on the approach but was to land after the Delhi flight.
"However, the pilot of the flight from Delhi contacted the ATC, saying the Hyderabad flight pilot was arguing with him over landing. In the process, the two aircraft came at a distance of 3,100 feet though they were in the required vertical separation limit," sources added.
No one from the airlines was available for comment on the incident.
