A special concession was given and Tejas did do the flypast once.But IAF should come out of past, and in fact push for Teja flypast as it will give confidence to other buyers and forces. If India take pride and confidence on Teja, then it must show it, saying is not enough.
It is not about Tejas or M2K. It is about single engine aircraft. M2K has served us so well. It’s participation in a flypast is not what would govern how good it is but it’s performance where it matters where it has done wonders. Professional forces don’t buy airplanes for show but to fight wars. They evaluate a system based on what is there inside rather than if it was on a display or not. It doesn’t really matter if there is a troll thread on pdf about flypast in Delhi.
