Climbing two of the tallest mountains on Earth is an amazing feat all on its own. But, imaging doing that without arms or legs. Kyle Maynard did, becoming the first person to scale Mount Kilimanjaro and Aconcagua without limbs or prosthetics. He was born with a rare condition called congenital amputation. It stopped his arms from growing beyond the elbow, and legs near his knees. Maynard is the keynote speaker tonight to kick off this year’s Flagstaff Festival of Science. He spoke with KNAU’s Aaron Granillo.
