I was in there today myself as well dropping the sister at the airport and seen them working away! I thought the building work was actually dismantling for the terminal/security improvements.
Also done a spot of airplane spotting down by emergency gate 8? Mum wanted to see my sisters flight off and I decided I'd take some pictures to update the Wiki page. I'll send you a link to them in due course. A number of other cars appeared whilst I was there too, you don't happen to drive a Fiesta or a Golf Carn?
