Dean Potter died today doing what he loved in Yosemite National Park. Here is a rerun of an interview we did with Dean last June: Dogs are loyal, brave and love to go wherever their owners do. Climber, BASE jumper and wingsuit flyer Dean Potter took truism to its logical conclusion when he would bring his faithful companion Whisper, an Australian cattle dog, climbing with him throughout Yosemite National Park, which is Potter's backyard playground. For the past decade, he's been perfecting his wingsuit flying abilities and decided to share his love of flying with Whisper, sharing their gravity-defying activities in his new film, "When Dogs Fly".
