DRDO has many faults, just as any other organisations in India. However, the author of the said article is a miserable ignorant agent of the corrupt sections of the India's armed forces' officers, bent on making quick bucks from the weapons purchases abroad. At the time, India embarked on developing its own missiles, nobody in the world would even sell automatic rifles to India, let alone sophisticated missiles. Speaking about re-inventing wheels, the author of the above article is still does not know the details of the mathematical processes involved in the concept of wheels. These people should better spend their time with free alcoholic drinks in their parties with the foreign journalists. The subject he has taken up here is well beyond his brain power.
