The incident had occurred yesterday at around 7 pm when the Indore ATC cleared the Delhi-Indore flight of SpiceJet for landing. Around the same time, the airline's flight SG 1053 Hyderabad-Indore 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.
There were around 160 passengers on-board at the time.
SpiceJet spokesperson was not available for comment.
