It is Noi Bai for sure, and they have a lot of planes painted that way at the gates, and that seems to match Vietnam Airlines.
So what does this mean? Does it connect to the arrest in Shanghai? Seems doubtful, no point in capturing them in one country and fly them out of a bordering country, on a public flight at that.
So, assuming a plane does not go down or missing and there is no incident, then why post this? Are we meant to track it?
If we know the airport and airline and time it took off (if we assume it was when Q posted it) maybe we can come up with a small list of candidate flights??? Planefags, where are you?!
