The US Air Force’s F-15E Strike Eagles performed twists and turns to the stunning backdrop of a series of valleys between Dolgellau and Machynlleth.

The area is used mainly by the British and US militaries as a low-level training area.

Pilot Major Thomas Morrill, from the 492nd Fighter Squadron based at the Suffolk airbase, said: “The reason we fly low in the F-15E is to practice a combat skill that allows us to get in to a target area using ground features like hills, mountains, and the curve of the earth to shield us from enemy radar, visual observers, and missiles.

“It is a perishable skill, so we have to practice to stay good at it.”

Aviation enthusiasts and photographers gather to marvel at and capture the skill of the pilots, who can fly their aircraft as low as 500ft.
