Nearly 330 passengers had a narrow escape after two IndiGo planes averted a mid-air collision over the Bangalore airspace on Tuesday, prompting authorities to launch a probe into the incident, industry sources said.
The Hyderabad-bound plane had 162 passengers while the other aircraft was carrying 166 passengers.
Sources told PTI that the vertical separation between the two aircraft was only about 200 feet and a mid-air collision was averted after the Traffic Collision Avoidance System (TCAS) alarms went off.
Sources said Aircraft Accident Investigation Board (AAIB) has started an investigation into the incident that happened on July 10.
In a statement issued in Bengaluru, the BIAL spokesperson said an incident involving two A320 aircraft operated by Indigo Airlines occurred in South Indian airspace on July 10 some distance away from Kempegowda International Airport, Bengaluru.
Pilots on board both aircraft were alerted to the presence of the other by on-board systems and, subsequently reported the occurrence to the DGCA in accordance with standard operating procedures," the spokesperson added.
