These jets are from RAF Valley where Royal Air Force fast jet pilots train and hone their skills before moving onto frontline fighters like the Typhoon and F-35.
This video was shot on 31st July 2018 from Bwlch Spur in the now famous Mach Loop, a circular route which is part of a bigger low fly area (LFA7) in the North Wales Military Training Area.
The Mach Loop is so called as it passes near to the town of Machynlleth, and is a circular system where pilots often go twice around. The USAF pilots often refer to the loop as 'The Roundabout' relating to the often chaotic British road junction of the same name.
