Its really amusing to see some members being so stuck up on the word "indigenous"! Really!!?
In the pure sense of the term, NO, none of the technologically advanced products any country makes are "indigenous". Blatant copyright infringement and copying does not count as indigenous, no matter what some may claim to be otherwise. So there it is. Its also highly amusing and ridiculous that many here come up with really ridiculously absurd numbers, quoting them as percentage "indigenous". How people come up with such 'interesting' numbers is beyond me! Get a life people.
The important thing here is India is developing industrial capabilities to design and manufacture such technologically advanced products, considering the fact that Indian economy was originally envisioned as an agrarian one!
Indigenous is a very relative term. In the context of Indian made products, especially in this case of aircrafts, "indigenous" means the capability to design and manufacture the product in India. Period.
