O bhai jaan itne serious na ho, i accept defeat. but try to look the other picture too, did we made the KLJ-7,RD-93, SD-10, C-802 for JF-17 all in all the big question comes in did we alone made the whole Jf-17 aeronautical design? nah it was jointly produced and developed. India being a 3rd world country has excelled something if we keep our Pakistan-ism and patriotism a side. Now could you please help me in finding out that Indian's designed the TEJAS aeronautical design or Russia helped them like the way China and Pakistan did?
