You cannot challenge video evidence from international reporters. The condition here is of n-1, not of n+x, we have n number of declared aircrafts, we should show all the n numbers and prove it is not n-1 (the case of 1 getting shot down) to international reporters who will video it, and hence will be proven. Whereas, in the case of North Korea, you don't know the if the declared number of nuclear facilities are true or not; you fear they are more, no matter how many they show you, you still wont know if that x is 0 or more in n+x.
Secondly, bad analogy, Pakistan's media is nowhere near as restrictive as North Korea, way off. Pakistan's media is rated as restrictive as that of India. Go figure.
Take this post with a grain of salt, a tweet from a person is not 100% valid ever.
