MOSCOW, November 3./TASS/. There was no danger of mid-air collision of two passenger planes on Thursday evening, a spokesman for the Russian Federal Air Transport Agency (Rosaviatsia) told Tass in comments on media reports that said referring to emergency services that two Boeing passenger planes flew dangerously close to each other over the Russian city of Ivanovo.

Russia’s State Air Traffic Management Corporation confirmed this information to Tass, explaining that the incident came because of an unsanctioned descent of a Turkish Pegasus Airlines’s plane in mid-air between Podolsk and Klimovsk (located 55 kilometers south of Moscow and eight kilometers south of Podolsk).

"There was no danger of the two planes’ colliding," Sergei Izvolsky said, adding that reports saying this could have led to an accident were not true.

An official representative of Russia’s State Air Traffic Management Corporation, Nikolai Ivashov, told Tass that the airborne proximity warning indicator went off on board the passenger airliner of Pegasus Airlines. The incident involved the Pegasus Airlines’ plane flying from Istanbul to Moscow’s Domodedovo airport and a Russian Utair airline’s plane on its way from Moscow’s Vnukovo airport to Chechen capital Grozny.

The warning system went off as the Turkish plane began an unsanctioned descent from the altitude of 3,650 meters to 3,350 meters, while an Utair plane was ascending to an altitude of 3,350 meters, Ivashov said.

Ivashov said the planes passed each other successfully due to prompt actions of air traffic controllers. There was no danger of mid-air collision, and the incident is looked into, he added.
