Can Tejas do this? . You do know IAF is known as the flying coffins air force right? World famous.
You can claim it's a cover up but still doesn't change the fact that Tejas is a shitty pplane.
Very few of Western fighters do that maneuver : Pugachev Cobra. Its a marketing gimmick and not a necessary condition for a modern fighter aircraft. Does not have much practical use in modern age of BVR fighting.
