Point taken Shy Torque, the profile doesn't fit your supposition I'm only trying to illustrate just how the built environment catches folk out. Having had more than one hot air balloon wrapped round my gable end and seeing the oil streaks on the underside of a light twin as he carved his way down the street. Any lower and he'd have had to stop for the traffic lights at the top of Mutton Hill. A 1500 hour mate of mine flying from Netherthorpe and Gamston is very well aware of the gotcha presented by the feature. Nottinghamshire isn't on everyone's radar as presenting a possible terrain hazard.
