The veteran naturalist examines the world of flight, travelling across the globe to chart the evolutionary story of those creatures who seemingly defy the rules of gravity by taking to the air. Initially focusing on insects, Attenborough meets a descendant of the dragonfly, before examining the Atlas beetle, which tends to restrict flight to times when it needs a mate or a fresh supply of food. More aesthetically pleasing is a group of beautiful tropical butterflies, followed by an in-depth study into the blow fly - the jet fighter of insects

The veteran naturalist visits the jungles of Borneo to meet creatures that like to glide through life - the harlequin tree frog and the little-known colugo - often referred to, incorrectly, as a flying lemur.

He begins with the vast bird family, watching a group of vultures as they go scavenging and some peregrine falcons dive bombing for their prey. He then moves on to the floating forests of Ecuador to find out what makes the humble hummingbird tick, before ending his journey at the Gomantong bat caves of Borneo - a place he first filmed in 1972 - witnessing a mass exodus of the creatures
