A photographer has captured the moment American pilots held the Welsh flag up to plane spotters whilst taking on the famous Mach Loop.
The images were captured by Ben Webb at the world-famous spot between Corris and Dolgellau, which is a mecca for plane spotters, with aircrafts using the mountains for low-level flying exercises.
