A Russian MiG-29 fourth-generation fighter jet crashed near Moscow on Thursday, injuring one of the pilots, the Interfax news agency reported.
The plane was a training model with two seats. Both pilots ejected before the plane hit the grass near Chemodurovo, a village southeast of Moscow. One was airlifted to a Moscow hospital, the agency reported, citing local police. No one else was injured.
The plane, a version of the famous 1980s Soviet jet, was owned and operated by its manufacturer, the Mikoyan aircraft design company, a source in the Defense Ministry told Interfax.
The Russian air force does not operate planes that model, and the crash will not affect military flights, an unidentified military source told Interfax.
Russia's Investigative Committee announced on its website that it had already seized company documents, and plans to survey the crash site and take fuel samples as part of an investigation into the crash. The case is being pursued as a possible breach of transport safety laws.
Investigators are looking into the possibility of technical fault and pilot error, news agency RIA Novosti said.
