As it transpires, this programme's bit of a misnomer; there's precious little Wallace and Gromit in it, more beardy men in coats flapping about. That aside, we're willing to give it one more whirl. When it comes to inventing, the skies are the limit, as world-renowned inventor Wallace and his faithful camera hound, Gromit, discover in the second episode of their series looking at some real-life cracking-contraptions, from gadgets that help around the home to the mind-boggling world of space travel and much more in between. Tonight, the intrepid pair explore the mysteries behind man's fascination with flight, from homemade space rockets in Manchester to personalised jetpacks. Wallace introduces Steve, inventor of the first-ever privately funded rocket built to carry people into orbit. A former toothpaste inventor with a fine line in homemade rockets, Steve unveils what he hopes will be his finest invention yet. Plus, Jem Stansfield travels to California to investigate the connection between David Beckham and an eerie-looking spherical airship.
