>>>Another Russian Air Force Tu-95MS strategic bomber has crashed in the country's Far East, coming down on Tuesday during a training flight. This is the sixth crash suffered by the Russian Air Force in recent weeks. This follows both the crash of another Tu-95MS in June and the subsequent grounding of the fleet. The Russian Air Force has suffered a string of recent crashes, a result of high operational demand and under investment in sustainment. Following two crashes earlier this year, the fleet of MiG-29 fighters was grounded earlier this month, with further accidents also leading to the grounding of the Su-24 fighter fleet in July. A Su-34 also came down in early June, bringing the total number of aircraft types involved in recent crashes to four. >>>

Ökad flygaktivitet och kanske pilotutbildningen?
Eller bara slumpen?
