Thomas must collect a group of children from the Airport, and take them to the Sodor Summer Picnic. When Thomas arrives at the Airport, he meets a new Jet Plane for the first time, named Jeremy. Jeremy comes off to Thomas as being rather boastful, when he says how splendid it is to fly high in the air, and so Thomas decides he won’t be talking to him again, anytime soon!
