I used to verfly the 2 by the railway line quite often. The one north of the railway looks rough as a bears a**e but the one south of the railway looks smooth as a babys. Never saw any movements on either, nor any parked a/c.
My instructor told me that both were strictly PPR and that the owners were not happy about unwanted guests - I presume due to planning limits.
They are both easy to find being about 2 miles due SE of the frieght terminal and bisected by the railway line.
