Blue Peter: Astronauts, Pentatonix and Jedward

We're flying high on this week's Blue Peter as Barney comes face-to-face with the world's largest passenger airliner, the Airbus A380. He follows the epic journey of the huge wings which begin life in a factory in North Wales and travel all the way to be assembled onto the plane in Toulouse. With only inches to spare from crashing into houses in small French villages, it's a delicate delivery process. And from planes to pranks, CBBC stars Sam and Mark are live in the studio, to explain all about their new series of Friday Wind Up, and show everyone at home how to make their very own game of skittles.
