so your saying two things:
1. Pakistan couldn't track this missile without Chinese help as if Chinese officers were in the ground helping us...yes, these were most probably PAF's AWACS and radars of Chinese origin but "Chinese help" means that Chinese were physically involved.
2. indians would waste a perfectly good missile just to test how far can their missile go thru the Pakistani defences only to crash 70 or so miles away from a "sensitive installation" as you put it which presumably means the Rafique Airbase which may we be surrounded by HQ9 batteries while knowing full well that true test would take place when it was actually in range of the air defences and then see if the defences can stop it or not?
I mean, never mind the fact that our Military will naturally hide its true capabilities but doesn't it strike you as even slightly odd that the missile just happened to have gone down in a place where it would be well within the range of our SAM batteries? if you were expecting it to get intercepted right after it entered our airspace, I'm not that's not possible, yet at least. the 16 air defence regiments that have armed with HQ9 and HQ16 batteries are used to protect sensitive installations, heck even a country as rich as kaA couldn't cover every inch of their airspace, they've had missiles reach all the way to riyad before interception took place, that's the capitol for God's sakes, even Russia can't cover every inch of the airspace over Syria with their s400s...you are really not giving our forces enough credit here...
