By coincidence, Russian President Dmitry Medvedev was due to attend a political forum in nearby Yaroslavl on Thursday so top Kremlin officials were already in the area which is around 150 miles northeast of Moscow. Accident investigators said they were looking into all scenarios but that it was not immediately clear whether the crash was the result of pilot error or technical failure. Although Russia has used some of its windfall oil revenues to buy new Western planes in recent years, hundreds of ageing Soviet-era planes remain in service....the plane involved in Wednesdays crash had only been flying since 1993.
