"Another black day has appeared in the history of Russia," said the tabloid Tvoi Den, which also reported that President Dmitry Medvedev had cancelled his 43rd birthday celebrations on Monday because of the tragedy. In a bid to stave off further reputational damage, Aeroflot chief executive Valery Okulov said earlier that the Aeroflot Nord airline to which the plane belonged would have its name changed, Echo of Moscow radio reported on Monday. Aeroflot Nord, which is based in the northern Russian city of Arkhangelsk, was also said to be under investigation, Vesti-24 television reported. A spokesman for Aeroflot Nord denied the company would change its name. The firm flies to 26 cities in Russia and is 51-percent owned by Aeroflot. The airline earlier confirmed there were no survivors and said the dead included nine people from Azerbaijan, five from Ukraine and one each from France, Germany, Italy, Latvia, Switzerland, Turkey and the United States.
