The Zip Aviation helicopter was on its way to pick up passengers around 1:20 p.m. when it hovered and then plunged into the river near 30th Street and the Lincoln Tunnel.

“It did like a spin, I guess the wind caught it, and it just went right into the river,” witness Jack Linkin told CBS2.

“I heard a big loud sound, and then it started spinning out of control and coming down back into the water. That’s when the airbags deployed,” said witness Cat Lund.

“My heart started beating very fast and I was just thinking if anybody was alive,” witness Mariana Vinhas said.

The 35-year-old from Mendham, New Jersey was rescued moments after emerging from the mangled aircraft. He suffered only cuts to his hand.

“He was able to wear his flotation device. He was able to get out of his helicopter and stand on the pad,” NYPD Assistant Chief Steven Hughes said. “There was a passing boat that picked him up and brought him to the heliport.”

All of the recovered pieces were taken by boat to Brooklyn.

“I’m shocked. I’ve never seen anything like this. I thought it was almost like a stunt at first,” said witness Anthony Rainsly.
