Saw it at EGPH parked at the southern end of 30/12 on Saturday night.
I'm not sure if it is still there but any spotters who want a good picture will get one by heading down Turnhouse Road towards the Cargo Terminal. Just beyond the farmhouses on the left is a road that gives access to the farm. It's public so no problem using it. It takes you across the railway line and brings you out near the threshold of 30.
A few weeks ago I went here to see the Spitfire, Hurricane and Lancaster getting ready for the airshow at East Fortune.
