Switzerland's answer to the RAF's Red Arrows have mistakenly performed a flypast above a yodelling event, four miles from where they were meant to be.
The Swiss Air Force's aerobatic team, known as the Patrouille Suisse was due to pass over Langenbruck, honouring the centenary of Oskar Bider's death – the first person to fly over the Alps in both directions, in 1913.
The Red Arrows were given the approval to perform after being granted a Public Display Authority (Picture: MOD).
However, the aerial display team missed the birthplace of the flying pioneer, 100 years after his passing.
Instead, the squadron headed toward the festival tents of Mümliswil’s 31st North West Yodelling festival.
Those attending were then treated to an accidental display by the Patrouille Suisse's F-5E Tiger II aircraft, which it is thought did not contain GPS technology.
The Swiss Defence Ministry has apologised for the error.
