Russian Prime Minister Vladimir Putin will on Wednesday attend the six-day air show MAKS-2011 that opened in the Moscow Region town of Zhukovsky on Tuesday, the government press service reported. Putin will speak before the show's participants and guests and get familiarized with aviation and space expositions of domestic and foreign manufacturers. A number of commercial contracts will be signed in his presence. Those attending the air show will be able to see for the first time Russia's new stealth fighter jet Sukhoi T-50, also called the PAK FA, which is meant to be a rival to the U.S. F-22 Raptor. The new jet made its maiden flight in the Russian Far East in January 2010.
