Footage by the Lake District Aviation Facebook page has captured the moment a US fighter jet soars over a Cumbrian reservoir.
The Lake District's military flights generally follow three main routes within LFA 17. The first is the Windermere–Thirlmere–Keswick route, also known as the 'M6 pass / Thirlmere route'.
Military aircraft enthusiasts have been spotting an increase in activity throughout the country, including the Lake District.
