Admiral Karambir Singh, the Chief of Naval Staff and the first helicopter pilot to occupy the august post, created history of sorts on the National Defence Academy (NDA) campus in Khadakwasla near Pune, sources said here on Friday.

Admiral Singh reached the NDA campus late on Friday afternoon, well in time for the passing out parade (POP) scheduled for Saturday, which he will preside over as the chief guest in the globally acclaimed tri-services academy.
