A salvage company brought the boat out of the water at about 2:45 p.m. and loaded it onto the company’s barge. The company will bring the boat to shore for closer inspection.

From Penn’s Landing,  200 yards from the accident site, the only sign of damage visible was a crushed canopy, but there could be more damage to the side of the boat that couldn’t be seen.

One passenger, 16-year-old Dora Schwendtner, was found at 4:45 a.m. downriver from the accident site. A fisherman found her near the Walt Whitman Bridge on his way out for the day, the Philadelphia Inquirer reported.

The body of the other, 20-year-old Szablcs Prem, was recovered by the Philadelphia Police Department’s marine unit at about 3:10 p.m. It was first spotted around 9 a.m., before his body drifted underneath the salvage company’s barge. The current was too strong for the police to recover the body until after the barge moved.

Both were Hungarian citizens visiting the United States on a church program, the Inquirer reported.

Although the Philadelphia Police Department’s work is almost done, NTSB still has much ahead of it. Board members Robert Sumwalt and newly-approved Dr. Mark Rosekind came to Penn’s Landing around 2:30 p.m. Friday to watch recovery action.

NTSB Lead investigator Tom Roth-rothy spent much of the day onboard a local Coast Guard boat, observing recovery efforts.

Rosekind and Sumwalt spent much of the time in serious talk with local police and Coast Guard officials and were there when the second body was recovered.

NTSB declined to comment until tonight’s press conference at 8 p.m., where they will discuss findings from today’s investigations.

Check back later tonight for a series of photos from today’s work.

But board member Robert Sumwalt, the only one to speak at the press conference, spent more time telling local media that NTSB still has few answers and it will be a long time before some of their most pressing questions are answered.

Thirty-seven people were thrown into the Delaware River Wednesday afternoon when a barge collided with the amphibious duck boat they were on. Thirty-five people were immediately rescued.

The U.S. Coast Guard suspended the search for the two missing people on Thursday night.

When a television reporter asked Sumwalt what he thought about tourists getting mixed up in an accident involving the industry side of the marine sector, Sumwalt’s only response was “It’s tragic.”

At the time of the collision, the duck boat was at a halt on the river, waiting for assistance after a reported engine fire disabled the engine. A tugboat was pulling the barge.

NTSB is taking the lead on the investigation and questions are being deferred to board member Robert Sumwalt and lead investigator Tom Roth-rothy, who are in Philadelphia supervising the investigation team.

Sumwalt said that NTSB expects to have investigators on the scene for seven to 10 days total, meaning they could depart as early as the end of next week.

Investigators will take all of the data and information collected and bring it back to Washington, D.C., where NTSB is headquartered. It will likely take several months to put all the pieces together and determine everything that went wrong Wednesday afternoon.

While on the scene, investigators will be gathering all kinds of information and data on the actual boats involved, their operating procedures, their crew members and their emergency preparedness and response. That will come form actual inspections of the boats, records and equipment and extensive interviews with passengers, crew and first responders and rescuers.

For local coverage of the accident, you can check out the Philadelphia Daily News and Philadelphia Inquirer at www.philly.com. Thursday’s main story on the accident focuses on confusion about why the tug boat was unaware of the duck boat’s presence.

It’s a popular summer pastime, but its popularity makes marine safety officials nervous. The National Transportation Safety Board has had a standing recommendation to the states to improve their recreational boating safety since 1983.

Nowadays, the chief concerns are life jacket use — two states still don’t require life jacket use, period — and boater education requirements. As of Jan. 2010, 13 states did not require any sort of boater education before getting behind the wheel of a boat.

According to 2008 recreational boating statistics from the Coast Guard, 79 percent of recreational boating deaths happened when the person operating the boat had no official boating instruction. And according to NTSB officials, about 75 percent of boating accidents happen because of things that are in the operator’s control.

If you want to learn how to boat safely, or want to brush up on your skills, the National Association of State Boating Law Administrators has a thorough database of local boating safety courses.
