Today was presented a new series Russian aircraft МС-21. Aircraft wings made of carbon fiber. Carbon fiber is lighter than aluminum and almost not subject to corrosion. Because of this, it became possible to reduce fuel consumption and increase flight range of up to six thousand kilometers, which is a record for this class of aircraft. The price of the aircraft MS-21 - $ 70 million. While the price of a similar Boeing 787 is three times more expensive - $220 million. Boeing will have to reduce their prices for three times in order not to lose the market.
