Waterloo Road; Midsomer Murders
8pm, BBC1; 8pm, ITV1
Waterloo Road returns for a fifth series, with the school being forced to face down its merger with John Foster, its posher neighbour. No surprise, it soon gets all Crips and Bloods in the playground, not to mention in the staff room. In this respect, particularly look out for "Area Head" Max, a cross between David Miliband and Ian Curtis, who manages to dispense paranoia and sexual tension in equal measure. Midsomer Murders has its work cut out to match that, but if anything can, it'll be a Swiftian murder in the model village. Inspector Barnaby (John Nettles) gruffly investigates.
Andrew Marr's The Making of Modern Britain
9pm, BBC2
Marr's latest series on British history takes the death of Queen Victoria in 1901 as his starting point, and runs through to the end of the second world war. It's a time of political and social upheaval, where new ideas challenge the old order, and Marr makes a good job of flitting between high politics and the music hall to cover as much as possible.
Did Heston Change Little Chef?
9pm, Channel 4
Following on from Heston Blumenthal's attempts to invigorate the Little Chef roadside restaurant chain, the three Michelin-starred chef is back to see whether his efforts have made any difference. The promise was that if the experiment at the Popham restaurant was a commercial success, Little Chef would roll out Heston's changes across the country. Six months on and Heston – once he is allowed into the restaurant kitchen – finds that his recipes have been modified using cheaper ingredients. The clash of cultures reignites, even as the Popham restaurant is up for an entry in the Good Food Guide.
High Fliers: When Britain Took to the Air
9pm, BBC4
Hard to imagine now, with your knees jammed between seats as you pick at rubberised chicken with a plastic fork, that there was once a time when air travel was considered incredibly glamorous and romantic. The 1920s and 1930s saw the heyday of luxury air travel, though it was of course only for the rich – and the somewhat daring as well. It was adventurous socialites who helped to open up commercial flying around the world that paved the way for mass air travel and, eventually, the likes of Ryanair and easyJet.
