Mach Loop: The Valley of Fighter Jets

Nestled between the towns of Dolgellau and Machynlleth, in central Wales, is a series of grass covered valleys that is renowned the world over among photographers and aviation enthusiast for being one of the best places in the world to watch fighter jets in action. This area is referred to as Low Flying Area 7, but is better known as the Mach Loop. The Mach Loop, which gets its name from the nearby town of Machynlleth, is essentially a roundabout for low level air traffic that snakes around the mountain peaks. Aircrafts such as Tornados, Typhoons, Hawks and F-15E Strike Eagles race through the narrow valley, hugging the ground as it twists and turns around the mountains. The machines fly dangerously close to the terrain, sometimes as low as 100 feet off the ground, at speeds over 500 miles per hour. Viewers can get so close to the scene of action that during flybys one can clearly see the pilots inside the cockpits. A Tornado GR4 at Mach Loop.

Low flying is a demanding skill that can only be acquired through progressive training and continuous practice. The Royal Air Force uses several areas within the United Kingdom for low level flight training. Because low level flying can be noisy, they are distributed all around the United Kingdom, “to share any potential impact of this training activity as fairly as possible across all the population”, says the RAF . “The cool thing about Mach Loop, and why so many photographers climb those steep, muddy hills and often camp out to capture the action, is the variety of aircraft that flies by,” writes Tyler Rogoway for Jalopnik .
