Got to agree with all the above. I've flown open cockpit aircraft and gliders, aeros, etc without any problem, but completely freak out with Tall buildings, and cliffs. Strange though it may seem I can drive across bridges but couldn't walk near the edge. Telling me somethings been up for 50 years just doesn't help. I can just about climb a ladder to paint our upstairs windows but you can almost see my finger impressions on the ladder! Always used to use docking for working on tailplanes or delegated!
Mrs Mike Echo thinks it all a bit strange.
