The plane crashed at 10:25 a.m. Moscow time on June 9 while returning to base in the Moscow region from a routine flight, the Russian Defense Ministry said.
"A Defense Ministry commission is working on the crash scene," the ministry said.
Sukhoi Su-27 fighter belonging to the Russian Knights (Russkiye Vityazi) aerobatic demonstration team was on a mission involving six planes, a source with knowledge of the situation earlier told Interfax.
"The Russian Knights aerobatic team was performing demonstration flights this morning during the unveiling ceremony of a monument to Russian Aviators in the village of Ashukino, the Pushkino district. While returning to the base near the village of Muranovo, one fighter crashed, and the pilot`s fate is so far unknown," the source said.
The Su-27 (NATO reporting name: Flanker-B) is a Soviet/Russian 4th generation multirole all-weather air superiority fighter.
