Southwest Airlines 'Triple Crown One'

I'm not sure if this map is ok, as it is probably the exact same plane as Kevin has found at the terminal.

Perfectly OK. As long as it isn't the same long/lat at the same time just from a different angle you're ok.

Not just probably the same. AFAIK, except for the Shamu planes, there's only one plane with each of the other Southwest special liveries. (Shamu has three at a time, and I beleive has had at least 5-6 different planes bearing Shamu livery over time.

In general, I enjoy when we can 100% identify the same plane or ship in different places in different times. As kjfitz said, if you are just rotating the BEV view and seeing the plane in the same exact place, but a different angle, then that's a duplicate. But if you find it in a different location, even a different location at the same airport, then that's not a duplicate IMHO.
