Thank you for your thoughts.
I take the point that you "could" fly down a loch @ 2' AGL legally, why?
Poor demonstration of a point.
The point raised that you would have to climb up to aviod the dam at the end of the reservior is very well presented. What about the tracks and roads along either side of the lake/loch? Do people really spend this much time making a detailed recce of the area they are going to low fly in?, or do they just do it?
Flying low is not dangerous, clearly many operators do it in a controlled manner - its illegal if you are not correctly authorised -
fact
So why?
