BROOKLYN, NY — A former Junior Olympic boxer trying to kickstart his acting career by climbing five bridges in four hours fell to his death yesterday when he slipped from a cable on the Brooklyn Bridge.

Robert "Eternal" Landetta, 27, of Brooklyn, a pro boxer who fought in the 1988 national Junior Olympic Boxing Championships, was killed instantly when he plunged 500 feet to the ground below, cops said.

Robert "Eternal" Landetta, was killed instantly when he plunged 500 feet to the ground.

Ida Unsgaard, 23, a photography student from Denmark, captured the tragedy on film.

"It was pretty horrible," she said. "I was taking pictures and suddenly he started slipping and then he fell and hit the ground."

In addition to boxing as a lightweight, Landetta was pursuing a career as an actor and stuntman.

He wanted to set a Guinness World Record by climbing five bridges in four hours.

Friends said he appeared as an extra in "New York Undercover," the cable show "Oz," and the Jenny Jones show and in an music video for the rap group Wu-Tang Clan.

Landetta told friends he wanted to set a Guinness Book of World Records mark by climbing five bridges in four hours, starting with the Brooklyn Bridge.

His trainer, Darnell Canada, 40, said the fighter thought pulling off the dangerous stunt would make him a celebrity.

"He was climbing up there to get a job," said Canada. "He did this because he wanted it on his resume.

"He always wanted to be on the front page of a magazine," said friend Maurice Smith.

Landetta recruited Smith, 14, and Allen Cooper, 15, to videotape the stunt.

But as they, bridge workers and bystanders looked on, he lost his grip on a thick steel suspension cable and plummeted onto Front Street near Brooklyn's River Cafe.

"I was sad and I was crying," said a still-shaken Smith. "I couldn't believe my eyes — I couldn't picture him dying."

Landetta made a fatal mistake when he turned around to pose for a photo.

Smith said Landetta told friends he planned to climb the Brooklyn, Manhattan, 59th Street, Williamsburg and George Washington bridges.

"He said, "I'm going to be alright,' " Smith said. "But this time he didn't make it."

The teens said Landetta made a fatal mistake when he turned around to pose for Unsgaard.

"As he was climbing, she gave him the sign to pose and he started sliding down and he dropped," Smith said.

Canada said Landetta — who was getting ready for a bout in May — was a devoted dad to his 5-year-old daughter, Destiny, who he had sole custody for.

"He took care of [Destiny] 100 percent completely," the trainer said. "They called him father of the year in the neighborhood."

AFTERWORD:

Landetta, who'd "always wanted to be on the front page of a magazine," finally realized his dream by having his accident featured on the front page of this edition of the New York Post.
