Two gendarmes involved in a complex motorbike ballet with horsemen from the Republic Guard crashed into each other within yards of Mr Macron.
In one of the most keenly-awaited moments of the display, three sets of three jets were due to to trail the colours that make up the French tricolour flag - red, white and blue.
However, due to a mix-up in charging the canisters, one of the jets had been fitted with the wrong colour - red instead of blue - meaning the jets flew over with a lop-sided flag of white, red, blue and then red again.
Oh dear!
