Earlier this year, when the Chengdu J-20, China's fifth generation fighter prototype went from being a grainy internet rumour into a thundering reality, the Indian Air Force commissioned a report by a group of officers. The group was asked to study all available information on the aircraft, photographs, videos and any other material available. Folks from the Aeronautical Development Agency (ADA) and some academic institutions were asked to be part of the report too. I'm privy to a few excerpts from the final report, and will post those once my sources give me the all clear. Stay tuned.
