So what ?
maybe some of them have a few hundred hours or something on them and are the planes where the Indians were being trained on. Too much detail lacking here.. low resolution pic, can we identify if it's a trainer or single seat, where are the pics of all the rest of them to compare with.. ever seen a jet up close ? they're pretty messy, naval ones are filthy dirty and even AF and army ones in coastal climates tend to acquire a lot more grease and corrosion/weathering owing to the conditions.
windjammer is losing his touch.. debunked already on the fake Mirage elephant walk and tandem 4 take off threads, and now this really pathetic one.
also, please, nobody fool yourselves.. 36 is just an initial order. There will be a hell of a lot more of these added to IAF and maybe IN in the future.
