PEARL HARBOR, Hawaii (AP) — Tourist Shawn Winrich was taking photos of Pearl Harbor when he saw a helicopter "essentially coming straight at us" at the popular tourist destination.
He switched to video, recording the helicopter's dramatic drop into the water below.
"All of a sudden it essentially just fell out of the sky and crash-landed in the water," the Madison, Wisconsin, man said.
He stopped filming and jumped in to help.
The family of four visiting from Canada and the pilot on board made it out, but one passenger — a 15-year-old boy who was trapped underwater and had to be cut free from his seat — remained hospitalized in critical condition Friday.
U.S. Navy spokeswoman Agnes Tauyan said the helicopter sunk shortly after going down near the visitor's center Thursday. A 45-year-old woman and a 50-year-old man remained hospitalized Friday in stable condition. A fourth family member was treated and released Thursday. Details on the pilot, who remained hospitalized Friday, were not immediately available.
No names were released.
Another bystander who jumped in to help was tour guide Chris Gardner who was with a group at the Pearl Harbor Visitor Center when he heard the crash.
"I took off my shirt and dove in," he said, describing how he, a Navy sailor, a federal police officer and another man took turns diving to the submerged helicopter and trying to free a passenger with a knife. "He was strapped into his seat in the back of the aircraft."
Honolulu paramedics treated the 15-year-old passenger and took him to a hospital, said Shayne Enright, spokeswoman for Honolulu Emergency Services Department.
"It was a team effort and we pray that he's OK," Gardner said of the teen he helped free.
Jumping in to help is part of the instinct growing up in Hawaii, he said. His eyes were still burning from the fuel in the water, he said.
Winrich's daughter, Justice Winrich, said she watched as the helicopter plopped down into the water and saw three people get out immediately and swim to shore.
"It was crazy," she said. "You go on vacation and you never think you're going to see something like that."
Federal records show the helicopter is registered to Jeffrey Gebhard of Kailua, Hawaii. A man answering the phone at a number listed for Gebhard said: "I'm sorry, there's no comment. There's an investigation going on."
The Navy said the helicopter reportedly belongs to helicopter tour company Genesis Aviation. The website for Genesis Helicopters says it was founded by Gebhard.
The visitor center was closed Thursday but was set to partially reopen Friday. The memorial honors the 1,177 sailors and Marines killed on the ship in the Dec. 7, 1941, attack by Japan.
It was the second major crash this year involving helicopters on Oahu.
Twelve Hawaii-based Marines were killed when two military helicopters crashed during nighttime training on Jan. 14. Both aircraft were CH-53E Sea Stallion helicopters that were part of Marine Heavy Helicopter Squadron 463.
