The Return of the Master.........It is indeed the Revathi but quite how you tell the Mk I from the Mk II I'm not certain.
It was first flown in 1967 and lived a sort of ghostly existence until killed off in the mid-70's. The Indian Govt Auditor had some harsh words about the continued use of national resources when it was clear that the IAF didn't want it and had never been asked to offer any input to the original design... sounds familiar.......
