A Swiss fighter jet display team has performed a stunning fly-past - over the WRONG town.
The Patrouille Suisse - equivalent to the British Red Arrows - were due to fly over Langenbruck to honour the centenary of a Swiss flying pioneer.
Instead they surprised everyone at the nearby town of Mümliswil, which was hosting a yodelling festical.
A spokesman for the Swiss Defence Ministry has apologised for the error and said the aircraft has no GPS, relying solely on maps and a pen.
The squadron was due to perform for the 100th anniversary of the death of Oskar Bider.
Mr Bider was the first person to fly over the Alps in both directions, a feat he accomplished in 1913 at the age of 22.
The aviator was born in Langenbruck.
But the squadron leader saw the tents set up for the yodelling festival in Mümliswil, roughly four miles west of the town, and misdirected the jets.
A spokesman for the Swiss military told the German language Neue Zürcher Zeitung newspaper that the F-5E Tiger II aircraft were not equipped with modern technology.
He said: “Navigation is done on the basis of a map, a pen, and human sight."
The yodel festival patrons are reported to have enjoyed the unexpected show.
