Low Flying Wales Mach Loop
The Mach Loop (also known as the Machynlleth Loop) refers to a series of valleys in the United Kingdom in west-central Wales, notable for their use as low-level training areas for fast jet aircraft. The system of valleys lies 8 miles east of Barmouth and is nestled between the towns of Dolgellau to the north and Machynlleth to the south, the latter of which it takes its name from. The training area is within the Low Flying Area (LFA) LFA7, which covers most of Wales.
Aircraft which use the training area include Royal Air Force Tornado, Typhoon, and Hawk jets, as well as U.S. Air Force F-15E Strike Eagles, which are based at RAF Lakenheath in eastern England
