Pilots throw their fighter jets through the sky just a few hundred feet from the ground.
These brilliant images captured an F-15E strike eagle touring through the Welsh countryside.
The jet is trailed by a bloom of heat distortion and bright white wingtip vortices as it powers in the area known as the Machynlleth Loop.
Wingtip vortices are the rotating sections of air that are left behind a wing as it generates lift.
The photographer even caught the pilots at work in the cockpit of the plane, as they go about their business.
The Mach loop is located in a set of valleys in Wales near Barmouth and is commonly used as practise grounds for low-flying jets.
During low level training UK jets fly at a minimum 500 feet and at a maximum speed of around 500 knots.
