Watch 4 Insane Skydivers Jump From Top Of 1 WTC

We hope you've fully digested your breakfast, because you're gonna want to see this World Trade Center BASE jump video. This isn't some sort of crazy, elaborate Jimmy Kimmel-esque stunt; four New York men have been arrested for the BASE jump, which stands for "building, antenna, span, earth" and involves leaping off a structure and using a parachute to soften the fall. The daredevils jumped off the 105-story skyscraper on Sept. 30 last year.

Apparently, police have been investigating the jump for more than five months, after a Goldman Sachs security guard saw the jumpers and reported the incident. Since 16-year-old Justin Casquejo was also able to scale the tower and chill on the roof last week, thanks to a sleeping security guard and an overly-trusting elevator operator, the World Trade Center may want to amp up its security training.

The video, which was uploaded to YouTube yesterday, shows an amazing nighttime bird's-eye of New York City. The jumpers are shrouded in darkness. The first jumper doesn't soar down 1,300 feet of the tower until the 2:32 mark, which is pretty nail-biting for everyone involved.

The second diver has a camera attached to himself as he jumps off the massive structure and glides smoothly down to the streets of Lower Manhattan. The camera keeps recording as he hurriedly stuffs the parachute into a bag and turns the camera to his face for a split-second.

Marko Markovich, Kyle Hartwell, and James Brady, all residents of Long Island, and Andrew Rossig, of Slate Hill, N.Y., turned themselves in to authorities. (Hartwell was the lookout for the three divers.) They're being charged with third-degree burglary and second-degree reckless endangerment. Their attorneys say the men are all experienced BASE jumpers.

The men say they encountered no security guards on their journey to the top of the tower, which is obviously a serious red flag for the site.

“These arrests should send a message to anyone thinking about misusing a landmark this way,” Police Commissioner Bill Bratton told press. “They will be tracked down and they will face serious charges. Being a thrill-seeker does not give immunity from the law.”

The jumpers say they plan to donate any advertising dollars garnered from their YouTube video to families affected by the Sept. 11, 2001, attacks.
