Well, it seems I made a mistake - aren't you all proud to be present at such a historic event?
Rob set me on the right track - I had disabled the OBX94460 bgl, thinking anything with OBX in it must be related to ORBX. When, I don't recall.
Mind you, it looks pretty deadly. You can see where that shortarse tower is embedded, but needs another storey in height.
I will have a go at modelling the terminal, nothing fancy, just an exterior. There are plenty pics around, and buildings these days are very modular, so safe assumptions can be made about measurements etc - doors are standard heights, so you can work off them and get a reasonable representation. We shall see...
Thanks to everyone who helped
