Edmund Hillary, Edmund Shackleton, Marco Polo, and Neil Armstrong all accomplished feats that forever change humanity - breaking boundaries, redefining our limitations, and going where no one ever dared. But who was the greatest? We looked back at the feats of history's most prolific explorers on land, air, and ice, and picked our winners.
By Air (Round 3)
Winner - Fossett: Gagarin died at 34 flying a MiG-15. Fossett died in a somewhat less ballsy aircraft, but before that day set a ridiculous list of firsts. First to round the world solo in a balloon. First to fly a plane around the globe without stopping to refuel. First glider flight into the stratosphere.
