Russian pilots were trying to avoid a collision with the Boeing, reported Germany's news TV channel N-TV, citing a Swiss air traffic control center that guided the flight of both airplanes. According to its information, Swiss air traffic controllers warned the Tu-154 that a Boeing was heading towards it on a collision course. Russian pilots immediately changed their course to avoid a collision, but the Boeing's automatic safety system adjusted the course and that led to the tragedy.
Germany's electronic media also reported that the German air traffic control center had a radar recording of the air crash above the Boden See.
In the meantime, police found a black box belonging to one of the planes in a forest opening. Police helicopters keep searching for crash victims and for the hull of the Boeing-757, which collided with Tu-154 of Russia's Bashkir Airlines above the Boden See on the night of July 2nd. Both planes were flying at a height of 12 kilometres.
