The cover story of National Geographic magazine's September 2011 issue explores our quest to fly — from wing-suits to rocket-propelled jet packs to personal air vehicles. This video of BASE jumper Chris McDougall at Baffin Island launches off of the cover of the September edition of the magazine for iPad®. Also in the edition for iPad are a video of orphan elephants in an African sanctuary, an interactive map of Roald Amundsen and Captain Robert Falcon Scott's race to the South Pole in 1911 (along with archival footage from Amundsen's expedition), and a then-and-now interactive comparison of a New Orleans street ""portrait"" shot in 2006 and then again in 2011. The September edition for iPad is available on the App Store(SM) now. iPad is a trademark of Apple Inc., registered in the U.S. and other countries. App Store is a service mark of Apple Inc.
