The UFO

Plot
Percy spots something very small flying in the sky, but it is too small to be an aeroplane nor a helicopter. Diesel suggests to Percy that it was an UFO (a spaceship with an alien from another planet). Percy isn't so sure about Diesel's suggestion; but when he sees it again, he is sure that it is a UFO! But, it turns out to be a man flying a para-glider, and Percy teases Diesel that he saw the UFO as well as the alien!
