Well. that took me back! Stridding edge and nethermost cove. I did a job yards from where this was taken and came very close to killing my entire crew - as one of my old instructors used to say to all of us going through training " you ran out of skill!". Its a nasty place even on a nice day - so hat off and well done.
Skids/Wheels. Its subjective. I like wheels others will like skids. Depends what your used to and the aircraft your flying. If I had to do this job in those coditions or worse, I would rather have wheels. Go find a Police pilot who has flown skids for years and he will want skids - perhaps. Horses for courses.
If you look very closely on Scaffel Pike you will find some yellow paint and a few aerials from when it goes wrong doing exactly this type of rescue - my first one ever [I was co-pilot so I ran out of words rather than skill!!!]. A long, long time ago..........
