The Real Magnificent Men in Their Flying Machines: A Wonderland Film, BBC Two, preview For most of us, flying isn't a relaxing experience. But in the bizarre world of microlighting, where enthusiasts head for the skies in their rag-tag planes, often patched together from household appliances and referred to by one fan as a "deck chair with a lawnmower attached," there's no better place to kick back than up in the clouds. This Wonderland documentary follows the stories of three sets of competitors who enter a microlight rally around Britain. Rather than simply head from A to B, the competitors must cover as much ground, and fly over the top of as many landmarks as possible in three days. It feels like an aerial Wacky Races as they dash off in their personalised vehicles, with little in mind by way of strategy beyond staying airborne. There's the father-and-son team, a pair of recently reunited old flying chums, and eccentric veteran Richard Meredith-Hardy, who has flown over Everest in his bespoke plane. Though the racers share a certain blasé bonhomie, the dangers are real - tales of deaths and injuries abound. But, from the comfort of the ground, these wonderfully maverick microlighters are a joy to watch. The Real Magnificent Men in Their Flying Machines: a Wonderland Film is on Monday 23 January on BBC Two at 9.00pm
