Russian Emergencies Ministry personnel inspect the crash site of a Tupolev Tu-154 passenger plane near Zelenovka village, some 140 km from Russia's southern town of Rostov-on-Don, August 25, 2004. The plane, carrying 46 people including eight crew, crashed soon after it sent out a hijack alert message late Tuesday evening. Two Russian passenger planes crashed almost simultaneously late on Tuesday, killing all 89 people on board in what investigators said was either a terrorist attack or simply a mysterious coincidence.
