Not many people know what it feels like to fly, but Ellen Brennan has been doing it for eight years. At just 18 years old, Brennan had already mastered skydiving and BASE jumping. It didn't take long before she graduated to the next best thing: wingsuiting. Brennan was the only woman in the world invited to compete in the inaugural World Wingsuit League, where she was crowned the Fastest Flying Woman in the World.

Haven't heard of wingsuiting? It's a sport where athletes leap off a plane or cliff and glide through the air at crazy speeds. The suit itself is designed to add surface area to the human body, allowing the diver to sail the air horizontally while steering. The flight ends by deploying a parachute. "It's something that shouldn't happen. It's not natural," Brennan says in the video.
Then why do it?
"When you land you have this feeling of relief and achievement and satisfaction... You have achieved something that no one else has done yet," Brennan told CNN in an interview last year.
She has jumped off some of the most treacherous peaks in the world, including those in Norway, Switzerland, China and France. Somewhat of a pioneer for the sport, she even left her home in New York and moved to Sallanches, France. Her home is in the foothills of Mont Blanc. Every morning she hikes up a peak of her choice and leaps off into the summit. Watch the video above to see Brennan in action!
