US Air Force fighter jets carried out a flypast over London, marking the start of the NFL London Games at the Tottenham Hotspur Stadium in the north of the capital.
Four F-15s, stationed at RAF Lakenheath in Suffolk, made an appearance before the Atlanta Falcons faced the New York Jets in the series' first fixture on Sunday.
The aircraft are operated by 48th Fighter Wing – the US Air Force's only F-15 wing in Europe.
Performer Marisha Wallace's rooftop rendition of 'The Star-Spangled Banner', the US national anthem, was briefly drowned out by the jets, which have a top speed of 1,875mph.
They are expected to be seen once more above the 63,000-seater venue on 17 October, when the Jacksonville Jaguars face the Miami Dolphins.
Flight rehearsals had been seen and heard across parts of the UK capital in the days leading up to the show.
A limited number of American football contests have been hosted by the UK each year since 2007, although the London Games could not put on a show at the Tottenham Hotspur Stadium in 2020 due to the COVID pandemic.
