Pillarisetti claims that the research from his article was used for a book on the same subject titled Operation Pawan (Manohar Publishers, 2015), written by Air Marshal Bharat Kumar. “There’s a lot of thinking about whether Sushant borrowed his research from Operation Pawan. But even if he did, he hasn’t referred to Operation Pawan in the book … My article didn’t get a mention, and nor did Operation Pawan. So the question: how did he get the material? … I didn’t want to say it outright, but people know what it is. There is so much content in that book that came from that article.”
