A fascinating portrait of a TV news pioneer. Plus! The DIY SOS team tackle a home-dialysis build. Here’s what to watch tonight

Whirlybird: Live Above LA – Storyville

9pm, BBC Four

The “eye in the sky” is a phrase familiar to anyone who has watched an LA thriller – the helicopter reporting team tasked with covering high-speed chases. This fascinating documentary tells the story of one of its pioneers, Zoey Tur, who spotted the potential for birds-eye reporting during the breaking news boom of the 80s and 90s. Interweaving the tale of Tur’s professional life with her coming out as transgender in 2013, we gain an insight into the toll her work has taken. Ammar Kalia

DIY SOS: The Big Build

9pm, BBC One

The team is in Barnstable for this week’s mission: Build a home dialysis centre so that the Collinses need no longer make four-hour round trips to the hospital to get life-saving care for their daughters. It’s a big job, but Nick Knowles and his army of local volunteers are raring to go with goodwill and bags of ideas. Ellen E Jones

Cornwall: This Fishing Life

9pm, BBC Two

An episode that is this whole series in microcosm: old traditions are still upheld at Cadgwith, the last full-time fishing cove in the county, but it’s being squeezed out by dwindling fish populations and bigger boats. Are a new generation of fishers a bright new hope, or merely a last hurrah? Jack Seale

Undercover Police: Hunting Paedophiles

9pm, Channel 4

Episode two of the grim docuseries following the efforts of law enforcement to apprehend suspected child sexual abuse offenders. Posing as a 13-year-old girl, the police set up a sting, while another alleged offender must address the thousands of disturbing messages he has sent to children online. Hannah J Davies

Film choice

Roxanne (Fred Schepisi, 1987) 11.30pm, Sony Movies Classic

An update of Rostand’s tragicomedy Cyrano de Bergerac, with the nasally challenged poet-warrior turned into Steve Martin’s fire chief with the big conk. The plot stays true to the play, with Martin yearning for Roxanne (Daryl Hannah) but wooing her on behalf of a dim young chum. It’s lots of fun and a proper love story. Paul Howlett
