Lockerbie: A Search for Truth
9pm, Sky Atlantic
Colin Firth stars in this drama about the Pan Am Flight 103 bomb that exploded over Lockerbie in 1988 and killed 270 people. Firth plays GP Jim Swire whose daughter was on the plane and who leads the search for justice – dedicating his life to finding out what happened. It’s gripping, well crafted and sensitively told, but there’s no escaping the palpable dread in this opening episode, which starts with the night of the bombing. Hollie Richardson

They battle it out against question master Jimmy Carr, with the help of Mitchell Brook primary school (adorable) and Charles Dance (austere).

The Sweets & Treats We Loved & Lost
9pm, Channel 5
It sounds like a pub conversation that someone has turned into a TV documentary. But this two-part nostalgia trip also functions as a lighthearted history of British confectionery as contributors including John Sergeant, Janet Ellis and Christopher Biggins recall the Toffos, pear drops and Spangles of their lost youth.
