R&D Institutes in India are nothing but a huge money sinking mechanism. I'm sure with the money spent on this costly toy, we could have bought 5 working pilotless aircrafts from Israel or France and that too in half the time spent on development. I think it's time our DRDO is made into a BPO. Saves lot of tax money!! Apologies / Salute to genuine scientists like our honourable APJ Kalam.
