A mysterious plane which appeared on radars but did not respond to radio messages caused alarm at Moscow air traffic control on Wednesday, LifeNews reported.
Questioning the pilot revealed that the plane, an Aero L-29 training jet, was traveling through clouds and it was likely that ice on the plane's body cut off the jet's radio.
"After exiting the clouds I tried to make contact with the zone center, changed frequencies, but it was all for nothing. Traffic in the Moscow air hub is very dense, so I decided to land at the nearest airfield to not create additional problems," the pilot, Alexei Shakhmatov, told the military.
The plane, which belongs to the Volunteer Society for Cooperation with the Army, Aviation and Fleet (DOSAAF), was traveling from Nizhny Novgorod to Stupino airfield where it was based, considerably further south of Moscow.
