Machynlleth Loop, more popularly, and relevantly for that matter, known as "Mach Loop," is a series of grass covered valleys in central Wales that is known the world over by photographers and aviation enthusiast alike for some of the best military aviation action viewable from terra-firma.

The whole area sits under Low Flying Area 7, and because of the terrain, fighters, trainers, helicopters, and even transports use the canyons to hone their low-level flying abilities.

Although it is clearlyflying low over the ground still has its tactical advantages when it comes to avoiding radar and other sensor systems. Paired with modern countermeasures like towed decoys and standoff jamming, non-stealthy and stealthy aircraft alike can use this tactic to infiltrate to their targets and make it back alive.

This is quite possibly the best F-15E Strike Eagle video of all time. F-15E cockpit videos are rare

Some aircraft, such as special operations C-130s and helicopters, along with the F-15E Strike Eagle, Block 40 F-16C/Ds and G44 Tornadoes,, even when visibility is down to zero or in the pitch black of night.

Low-level cockpit videos shot from inside F-15E Strike Eagles are surprisingly rare considering…

Even air superiority aircraft like the F-15C/D need low-level training as they could find themselves in that environment while hunting down an enemy helicopter or fighter, or running for their lives from a fight.

Beyond its tactical functions, flying low and fast is, well, really fun and challenging for combat aviators. The sensation of speed is not felt at altitude, but when you are sunk down between two canyons at 450kts that is another story.

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. The regulars are USAF F-15Es from RAF Lakenheath and RAF Typhoons, along with C-130s, Hawk Trainers, and various, but visitors do pop up, like A-10s or Saudi Tornadoes, or even

There is a good chance you have already seen some, and it helps that pilots know exactly where to pose for the cameras. Yet to really appreciate the action and the landscape, you have to check it out in video:
