Episode notes

Remember those days when it was possible to climb aboard a plane and jet off around the world? Well, while we might be yearning for foreign shores, there's no denying that air travel comes with a big ol' carbon footprint. But is it possible to make aeroplanes 'greener'? We chat to Dr Chiara Falsetti, a researcher at the Oxford Thermofluids Institute, who is looking at ways to improve the cooling mechanisms of aircraft engines, to boost their efficiency and ultimately make flying more sustainable.
