In the lead up to the US election President Joe Biden admitted to ‘screwing up’ in a debate against Donald Trump. His excuse? Several trips around the world, a cold and severe jet lag. Joe has Marnie and the panel wondering how we can fly better.

We’ll be stopping off to hear how one species, much like the US president, should consider reducing its airmiles, if only to avoid a pointless 16,000km round trip every year. There’ll also be a stopover in Northern Canada to hear how thinning ice is making it difficult for local communities to remain in touch with their ancestral heritage and traditional modes of travel.

Whilst we recommend considering more environmentally friendly alternatives here at Unexpected Elements Airways, we understand that some flights can’t be avoided. Take time whilst onboard to consider how you can reduce the symptoms of jetlag with tricks learnt from the latest scientific understanding of human physiology. Professor Rosemary Braun tells us how the clocklike rhythms of the body can be manipulated to make any long haul flights more manageable.

Also, the smashing specificity of Wimbledon’s grass tennis courts, a grand astronomical debate from the 1920s and a very special Nunavut Day.
