In a move to slash cost of aircraft production, India and Russia are planning production of two types of commercial aircraft in India. The move is expected to cut down the cost of aircraft production by 40 per cent, say media reports. Both the countries eye possible production of Russia's Superjet 100 regional airliner and a future Irkut MS-21 jetliner on the territory of India.    This was disclused by head of the Russian Economic Development Ministry's Asia and Africa department Yevgeny Popov in Moscow on October 4. The Russian-Indian inter-governmental commission for trade, economic, scientific, technical and cultural cooperation has started its 19th session in Monscow.    He also said that there is an opportunity to assemble planes in India. According to India's calculations, the cost of a plane built on the territory of India can be reduced by 40 per cent, he added.
