Whether NASA failed or not is irrelevant. Today the Pakis have an indigenously developed fighter (called JF-17 Thunder) while we are still waiting on Tejas and some how keeping those MiG-21s alive at geat cost of money and human life. It matters little which one has better specs on paper. The proof of the pudding is in the eating. Should we have a a military confrontation of a larger scale tomorrow with anyone, be it country or terrorist organization, our young men and women will bleed while the Babus of the Raksha Mantralaya will continue to eat mithai purchased from the money sucked out of coffin for our soldiers.
