After Bethan One crashes into the sea, George decides to build a new rocket out of aluminium and starts collecting cans. But his enthusiasm for recycling blinds him to Barney and Diane's desperate bid to start a family – and he ends up in an embarrassing misunderstanding with his own daughter Angela. George has to be rescued by the RNLI after his rocket crashes into the sea. It's too heavy to fly and George decides the best option is to start all over again. He goes with Barney to try and get some aluminium sheets from Lloyd, who runs a scrap yard. There's only one problem – Lloyd wants £150 and they're both broke. The Old Carriage Works team are murdered by Angela's school at rugby but as Tom tidies the playing field, George realises he could collect aluminium cans to use for a new rocket. He persuades Pam to let him start a collection at school – in return for helping with a model rocket competition. George is in a buoyant mood after Mary gets him a meeting with a recycling plant, but it's a bad night for his babysitters Barney and wife Diane when they discover she's not pregnant – again. Later, George finds the pregnancy testing kit and thinks it's Angela's. After an embarrassing chat with his daughter, George confronts Ed. Meanwhile a depressed Barney visits a consultant, missing his appointment at the recycling plant. George is angry and Barney resigns, while Diane is also hiding something. As the misunderstandings multiply, can the friendships and space programme get back on track? (thetvdb.com)
