ST. LOUIS (AP) — Video and audio recordings from a fatal tourist boat accident in Missouri show that the lake went from calm to deadly dangerous in a matter of minutes, the National Transportation Safety Board said Friday.

The NTSB cited preliminary findings gathered from the video recorder camera system salvaged by divers after the duck boat sank July 19 at Table Rock Lake near Branson. Seventeen of the 31 people on board died, including nine family members from Indianapolis.

The material was examined at a lab in Washington, but the agency has not yet analyzed the findings and no conclusions about the cause of the accident, one of the nation's worst maritime accidents in recent decades, can be drawn.

The findings, though, paint a chilling picture of the final few minutes before the boat went under.

The captain and driver boarded the vessel at 6:27 p.m. The excursion begins on land at a terminal in Branson. Normally, the vessel tours the popular country music and entertainment community first before going to the lake for about a 20-minute boat ride. The driver drives the vehicle on land, and the captain takes over on the water.

But the video recordings show that at 6:28 p.m., someone briefly stepped onto the rear of the vehicle and told the crew to take the water portion of the tour first. A minute later, with passengers boarding, the captain made a reference to looking at the weather radar prior to the trip.

The vessel arrived at the lake a few minutes before 7 p.m. and the captain briefed passengers on the location of emergency exits and life jackets, then demonstrated use of life jackets and pointed out the location of life rings.

The vessel entered the water around 6:55 p.m. at a time when the water appeared calm, the NTSB said. In fact, over the next five minutes the captain allowed four different children to sit in the driver's seat.

But suddenly just after 7 p.m., whitecaps rapidly appeared on the water and winds increased, the NTSB said. The captain returned to the driver's seat.

The driver lowered plastic side curtains and at 7:01 p.m. the captain made a comment about the storm.

At 7:03 p.m. the captain made a call on a handheld radio but the content was unintelligible. A minute late, an electronic tone associated with the bilge alarm activated, until about a minute later when the captain reached down and the alarm stopped.

The captain made another call on a handheld radio at 7:05 but the content was again unintelligible.

Over the next couple of minutes, water splashed inside the passenger compartment.

At 7:07 p.m. an electronic tone associated with the bilge alarm activated again.

At 7:08 p.m. the inward-facing video recording ended as the vessel was still on the surface of the water.

About eight minutes after whitecaps emerged, the video recording ended.

The audio quality varies widely throughout the recording, affecting the intelligibility of what is spoken.

  • About 18:27:08 - The captain and driver boarded the previously empty vehicle. The driver sat in the driver’s seat and the captain sat in the side-facing seat to the right of the driver. (The captain operates the duck on water and the driver operates duck on the road.)
  • About 18:28:00 - The crew was told to take the water portion of the tour first, by an individual who briefly stepped onto the rear of the vehicle.
  • About 18:29:13 - As the passengers were loading, the captain made a verbal reference to looking at the weather radar prior to the trip.
  • About 18:33:10 - The driver stated a passenger count of 29 and shortly after, the vehicle departed the terminal facility. The captain narrated the tour while the vehicle was in motion.
  • Starting about 18:50 - In the vicinity of the boat ramp, the captain began a safety briefing regarding the water portion of the tour. The briefing included the location of emergency exits as well as the location of the life jackets. The captain then demonstrated the use of a life jacket and pointed out the location of the life rings. The captain moved into the driver’s seat and the driver moved into the seat directly behind.
  • About 18:55:20 - The captain announced to the passengers that they would be entering the water. The boat entered the water. The water appeared calm at this time.
  • Between about 18:56:22 and 19:00:38 - The captain allowed four different children to sit in the driver’s seat, while he observed and assisted.
  • About 19:00:25 - Whitecaps rapidly appeared on the water and winds increased.
  • About 19:00:42 - The captain returned to the driver’s seat. The driver lowered both the port and starboard clear plastic side curtains.
  • About 19:01:01 - The captain made a comment about the storm.
  • About 19:03:15 - The captain made a handheld radio call, the content of which is currently unintelligible.
  • About 19:04:15 - An electronic tone associated with the bilge alarm activated.
  • About 19:05:21 - The captain reached downward with his right hand and the bilge alarm ceases.
  • About 19:05:40 - The captain made a handheld radio call, the content of which is currently unintelligible.
  • In the final minutes of the recording - Water occasionally splashes inside the vehicle’s passenger compartment. (The low frame rate and relatively low resolution make it very difficult to be more precise in the preliminary review.)
  • About 19:07:26 - An electronic tone associated with the bilge alarm activated.
  • 19:08:27 - The inward-facing recording ended, while the vehicle was still on the surface of the water.

Ripley Entertainment, the owner of Ride the Ducks of Branson, declined to comment about the video.

A private inspector who examined 24 duck boats for Ripley Entertainment in August, including the one that sank, said that when the bilge alarm went off, it would be a sign that, "There's a significant amount of water in the hull."

"It just wasn't getting evacuated," said Steve Paul, owner of Test Drive Technologies in the St. Louis area.
