Transcript for Arch Jumpers Not Jumping For Joy
And now, a group of athletes moving to a national park, moving at a velocity like being shot out of a cannon. But officials are stepping in. Here's gio Benitez. Reporter: These jumps are taking youtube by tomorrow. But federal officials are considering barring daredevil jumpers from this. It's a thrill that has cost lives. Last year, this man was killed when he hit the ground. The rope was too long. But this video, which has been seen more than 23 million times on youtube, was produced by Austin Baird. It can be just as safe as any other activity. Reporter: The team spends two hours securing ropes, tossing over a bag full of rocks to make sure it doesn't hit anything. We're talking about an 130-foot free fall. Then shooting back up another 100 feet. It's an adrenaline rush. And sometimes the risks have nothing to do with the jump at all. This man slips. The close calls are why tonight, aerial rope sports may have an end date. Still ahead tonight, the best pictures of the week.
