East Fortune is closed as an active airfield however they do open it occasionally for events such as the upcomming PFA fly in.
They did recently have an airshow but on the day I was there (Sat) nothing actually landed or took off from East Fortune, all traffic flew in from elsewhere.
They do however have an aviation museam on the sight which is an interesting place to visit.
