The S7 Sibir Airlines Airbus A320-200, registration VQ-BPL had been cleared by Air Traffic Control (ATC) to climb to 38,000 feet when, according to the aviation website, The Aviation Herald the incident occurred.

A trainee air traffic controller was in charge of the sector when the incident occurred

The Emirates Airlines Boeing 777-300, registration A6-EGQ operating as flight number EK-160 from Oslo Airport (OSL) to Dubai International Airport (DXB) was in the vicinity en route southbound at 37,000 feet. 

The sector both aircraft were flying in was under the control of Rostov-on-Don ATC, who had a trainee controller under supervision watching the air space.

An experienced controller looking after the adjacent air space noticed that the two aircraft were dangerously close and notified the trainee’s supervisor. The sector controller took action, turning the Emirates jet 50 degrees to the right while telling the Sibir A320 to immediately descend to 36,000 feet while also turning 50 degrees to the right. While the aircraft implemented their emergency procedures, the controller activated a short term collision alert.

At one point the planes were just 3.8 nautical miles and 500 vertical feet apart

According to automatic dependent surveillance-broadcast (ADS-B) transmissions, the Airbus stopped its climb at 36,775 feet and began its descent at 18:14:52Z. At this point, both aircraft were still on a collision course, just 22 nautical miles apart. A minute later, both planes reached their closest proximity with horizontal separation at only 3.8 nautical miles and a vertical separation of 500 feet.

Russia’s Southern Transport Prosecution Office has initiated an investigation into the near-miss.

While near misses happen more often than you might think, they rarely lead to anything catastrophic. Before the COVID-19 pandemic, there could be anywhere from 8,000 to 20,000 flights in the air at the same time.

What is striking about the near-miss over Russia is that there would not have been many planes in the sky. What this means is that the trainee and the person who was supposed to be watching him must not have been paying attention.
