Following on from my earlier post that it took 30 years to get a trainer aircraft into operation, reference; http://www.defenceforum.in/forum/mi...-30-years-design-aircraft-but-hope-still.html it still leaves unanswered the fact that modifying , copying or as China has often been accused of , Pirating existing designs available on the market, is a more practical way, quicker , less costly , functions and under no obligations to others, and is a better way than trying to design from scratch and taking too long and finally producing something which is by that time outdated or even available on the market cheaper, not to mention in a sense producing something which had by then already existed or we may say , in effect it was all an unnecessary exercise in re-inventing the wheel. can India really afford to play games in the laborotories when there are pressing defence needs and modification of existing foreign products would have been a better , quicker , less costly option ? in terms of producing DEFENCE EQUIPMENT from basic INDIGENOUS research and development , what indeed have been the results ?? most grateful if anyone could tell us , please ?
