Pilots transmitted 'Mayday' call, alerted Air Traffic Control of danger
According to sources, IndiGo's new Airbus A320neo was around 45 miles (approximately 72 km) from Kolkata when the pilots transmitted a "Mayday" call on radio.
This indicated to the Air Traffic Control that the aircraft and passengers were in grave danger.
