In the days of the old low level route in 1970 I once took my unsuspecting wife to Aysgarth Falls in North Yorks as it was a noted beauty spot. Having just done a low level nav course on JPs I knew it was also a turning point on said route. Spent a happy couple of hours sitting in the sun as a succession of aircraft including Vulcans, Buccs, JPs and even the odd Varsity passed overhead at 500' heading South, with the wife remarking that there seemed to be a lot of aircraft around today!
