Moscow hunts for body fragments, clues after fatal plane crash

MOSCOW, Feb 12 (Reuters): Emergency workers in Russia searched snow-covered fields outside Moscow on Monday, looking for body fragments and clues after a fatal plane crash a day earlier killed all 71 people on board. President Vladimir Putin has ordered a special commission to investigate what caused the AN-148 plane operated by Saratov Airlines to crash outside Moscow shortly after taking off for the city of Orsk in the Orenburg region, about 900 miles (1,500 km) southeast of the capital. Among the possible causes investigators are looking into are weather conditions, human error and the plane's technical condition. The plane's crew did not send any distress signals.
