A friend online says that the Russians have lost another MiG 29 at Ashuluk air base in Ashulik, Astrakhan Oblast which is home to the 185th Center for Combat Training and Air Force Combat Implementation. Ashuluk apparently has lost a few such fighters in recent months.
The fighter was sent out on a mission on Thursday (possibly to Ukraine) and did not return. No search party was formed so it is assumed that the Russians already know where it went down.
