COA have a maintenance facility on the Western edge of HOU. On this day there were many more planes visible than I'd seen there previously. Note the old art-deco original 1940s terminal for the airport.
There have not been many Dutch A320s, but Martinair had a couple when they still did shorter-range holiday flights. Seen lined up on the Polderbaan, PH-MPF is framed with that remote runway's auxiliary control tower. The aircraft went to Etihad in 2007.
