Filmed by our friend Dafydd Philips the cool video in this post shows 48th Fighter Wing’s (FW) F-15E Strike Eagles “making vapes” during low level training in Mach Loop Low Flying Area 7 (LFA7), Wales.
Noteworthy vapours are created by lift which generates a pressure differential above and below wings with the pressure above the wing being lower than the pressure below.
This drop in pressure is followed by a drop in temperature. If the drop in temperature passes the local atmospheric dew-point, then the invisible water vapour will condense into visible water droplets, as seen in this video.
The 492nd and 494th Fighter Squadrons based at RAF Lakenheath are the only two Strike Eagle squadrons in U.S. Air Forces in Europe (USAFE) and Air Forces Africa.
The Mach Loop (also known as the Machynlleth Loop) consists of a series of valleys in the U.K. in west-central Wales, which are famous for their use as low-level training areas for fast jet aircraft. The system of valleys lies 8 miles east of Barmouth and is nestled between the towns of Dolgellau to the north and Machynlleth to the south, from the latter of which it takes its name.
The training area is within LFA7, which covers most of Wales. Aircraft which use (and which have used in recent years) this training area include Royal Air Force (RAF) Airbus A400M, Tornado, Typhoon, Hawk jets and C-130J as well as USAF F-15C Eagles, F-15E Strike Eagles, F-22 Raptors, and F-35A Lightning IIs.
