Has anyone noticed a change at the airstrip?

There was a thread on undocumented patch changes on the official forums. Periodically trolls or yetis or troggs or someone emerge from a cave near the airstrip and fight a battle with the dwarves there.

I've heard reports from people who have visited the airstrip in its unpopulated state. I've never got round to trying to find a way in myself.
