Its a good job done, and they deserve our congratulations!. However we need to tremendously improve upon the speed, and also completion of projects within deadlines and within the budgets. When developed countries are sending their personnel and vehicles to other Planets, we take pride in having achieved a fraction of those! We take more than a decade to develop a working engine for our advanced combat aircrafts, and we are yet to see the light on this!. For example, by the time we finally develop this, the technology may become obsolete or outdated! Therefore we need to be quick, accountable, in absorbing and delivering hi-tech projects within deadlines & budgets, which will only help this poor/developing country, to save on crores of rupees which we invest every year in importing hi-tech items for our defences, etc.
