Actor Chiwetel Ejiofor joins Alex Jones and Matt Baker to talk about his new film The Boy Who Harnessed the Wind. Plus, Dan Walker shares plans for an RAF fly-past in honour of 10 US airmen who crashed in Sheffield's Endcliffe Park 75 years ago, and introduces us to Tony Foulds, a man who witnessed the crash as a child and has tended the memorial for 50 years. Justin Rowlatt investigates the police force so strapped for cash that officers patrol alone and half of roles are filled by civilians, and we find out what children and their parents think is the ideal way to spend half term.
