The Air Show; The Runaway Chair

With all sorts of aeroplanes and flying machines on display, it looks like being the best air show of all time! / Bill and Corky receive a new invention from Cedric - the Runaround Chair. How does it work? Bill and Corky won't know until they put it together. But with no instructions and a not-very-helpful Ned jumping in, the Runaround Chair soon turns into the Runaway Chair!
