To soon to tell, but suspicions run high that yesterday's crashes may be related to the Chechen conflict, although the government is playing down that possibility. For more, see this AP story:
" Officials made conflicting statements about whether the signal from the other jet indicated a hijacking or another severe problem on the aircraft. The Interfax and ITAR-Tass news agencies later quoted an unnamed law enforcement source as saying that the signal was an SOS and that no other signals were sent. Oleg Yermolov, deputy director of the Interstate Aviation Committee, said that it is impossible to judge what is behind the signal, which merely indicates "a dangerous situation onboard" and can be triggered by the crew during a hijacking or a potentially catastrophic technical problem. Sibir airlines, however, seemed to hint at foul play, saying on its Web site that it "does not rule out the theory of a terrorist attack."
