Earthflight is a British nature documentary that shows a flight from the view of the wings of birds across six continents, showing some of the world's greatest natural spectacles from a bird's-eye view. The BBC series was created by John Downer and narrated by David Tennant and consisted of six 60-minute episodes. The first episode aired on BBC One on 29 December 2011.
A two-hour subset of Earthflight was aired in October 2012 by the Discovery Channel in the US as Winged Planet. The entire series with rerecorded narrative aired on PBS, beginning in September 2013, under the title Earthflight, A Nature Special Presentation.
As explained in the sixth episode, some of the birds were imprinted on a human and filmed from an ultralight plane; others were filmed with a helicopter drone. Some other footage resulted from tiny cameras being strapped to the backs of birds.
