U.S. President Barack Obama and other leaders watch military aircraft fly past on day two of the Nato summit in Wales.
The RAF's Red Arrows were joined by fighters from the USA, Canada, Denmark, France, Germany, Poland, Portugal and the Netherlands.
The display was led by an RAF Typhoon flanked by two Polish Mig-29s, followed by a Voyager, the RAF's largest aircraft, and finished with a display by the Red Arrows.
