Russian President Vladimir Putin has flown aboard a supersonic bomber on the first day of the Moscow air show, which also featured a model of Russia's future reusable spacecraft.
Mr. Putin on Tuesday sat aboard a Tupolev-160 bomber as it carried him at supersonic speed to major air force and naval exercises in Russia's far north.
Russian space officials also exhibited a model of the "Kliper" spacecraft, which they say they expect to launch for the first time early in the next decade. The reusable spacecraft would be launched on top of a rocket and would carry as many as six people.
One of the companies present at the six-day event, the European Aeronautic Defense and Space Company, agreed to purchase a 10 percent stake in Russian aircraft maker IRKUT.
