The plane would have to be high profile. Perhaps this is something we really need to look into to hopefully cut it off before it happens by identifying plausible targets they would use. The list wouldn't be very long in terms of countries. We know they want to start conflict between the US and Russia so they would be using a Russian or Russian ally plane as their target likely a military craft or high profile craft carrying a high ranking individual.
I will start looking into this for possibles. Hopefully others do too because us finding this could:
1) Prevent WW3 (again)
2) If we can piece it together and make it public that would help expose the true enemy and make it easier to convince normies.
I think we need to double our efforts and figure this out given the magnitude of what happens if they succeed.
