USAF Seven Summits Team Preparing for Everest Climb

Some of you may already be familiar with Maj. Rob Marshall, who with Maj. Graydon Muller, leads the U.S. Air Force Seven Summits Challenge team. Their goal has been to reach the top of the highest peak on each of the Earth's seven continents.

With six down, there is but one more mountain to scale. However, it's Mt. Everest.

But these guys haven't set this goal just for the adventure. They are climbing for some very personal reasons, including honoring their fallen comrades. Learn more about Rob, the climb and his motivations from this recent Time magazine story.
