Russia investigates possibility of terrorism in plane crashes
BUCHALKI, Russia -- Russian emergency workers searched heaps of twisted metal and tall grass Wednesday for clues about what caused two airliners to plunge to earth within minutes of each other, killing all 89 people aboard. Officials said one jet sent a hijack distress signal. Flight recorders from both planes were found and taken to Moscow for investigation, ITAR-TASS, a Russian news agency, reported, indicating the question of what caused the twin disasters soon could be answered.
