Transcript for World Trade Center BASE Jump Video Released
Now to the video released overnight. Three B.A.S.E. Jumpers leaping off the top of one world trade center. The dare deafs turning themselves in and ABC's gio Benitez is in downtown Manhattan for us. Good morning, gio. Reporter: Good morning to you, robin. They say they did it for the thrill of it because of what this building means to them and to the nation. This morning a view like you've never seen before. Everybody has Ve a good jump. Reporter: Watch they're nervously sharing a last thought and then jump. It's the controversial and jaw-dropping video raising major questions. You see here their view as they plummet 104 floors from one of three daredevils who jumped off one world trade center in the middle of the night wearing cameras last September sparking fears of terrorism. A lot of people might be watching this and they'll say these guys are crazy. Everybody has their thing. This is our thing. We were thinking very clearly that everything was working out for us to make a clean, safe jump. Reporter: Watch the daredevils first pray. Thank you, baby Jesus. Reporter: Then they jump falling from 1,776 feet in the air. One B.A.S.E. Jumper glides through downtown Manhattan until reaching a deserted street and hides the parachute. This is supposed to be the most secure building on Earth. That's what officials said. So how did you get in? We found a spot where the cameras were not picking up and there happened to be a hole in the fence there, as well. Reporter: Was there ever a moment where you thought this might be disrespectful. Bead no intentions of being disrespectful to anybody and we weren't trying to hurt anybody. Reporter: An inside job. James Brady had worked construction at world trade center and knew exactly where to enter. Their stunt also caught on surveillance video which led police to the three jumpers and their lookout driver. Overnight the four pleaded not guilty to charges of burglary, reckless endangerment and violation of the local law. They could face up to seven years in prison. And they say police told them they had to turn themselves in. When a 16-year-old snuck in and climbed to the very top last week. Now, port authority which owns this site says the spirit of respect and reverence for this sacred site was violated, rob. As you heard him say that's the same building where that teenager just recently made it to the top. Clearly some security issues to work out and perhaps more cameras to install. That would be a big help.
