Mr Rao: The author have raised some valid points with some good reasoning. If he is wrong, please do write a reply with a point-by-point reply. Let us know the other side of the coin. DRDO and Kalam is praised too much in this country for the 'great services' they have done for this nation. But the truth is that they have not done anything great for the money spend. Ask any army chief, if you would like to. It is to be defined clearly whether DRDO serves the armed forces or vice-versa. In the name of secrecy, public is kept under dark about DRDO's so called achievements.
