The Mach Loop is a stretch of valleys in Wales that is famous for its low-level training flights. Photographers can stand on a ridge and watch airplanes flying below them. That’s a great view, but even better is this video: you’ll ride in the back seat of a Typhoon flying at 500 knots and pulling over 5 Gs, all while staying below the tops of the hills. It’s thrilling stuff, but requires intense concentration and serious training.
