The National Transportation Safety Board has completed its first full day of investigating the ‘Duck Boat’ accident on the Delaware.
Next, investigators will interview the crew of all the vessles to compile a 72-hour history looking at each crew members’ mental and physical condition leading up to the time of the collision.
Robert Sumwalt with the NTSB (right) says that information is key.
“We look back and see what was their lifestyle, how much rest have they gotten, what was their nutritional status, was there any stress in their lives, any unusual lifestyle changes.”
Investigators are also working on a timeline and sequence of events. Engineers are evaluating the electronic navigation data and evaluating any maintenance and repair. They’re also going to analyze scrape marks found on the bow of the barge.
Initial testing on the tug boat steering shows no problems.
NTSB investigators are expected to be in Philadelphia for up to 10 days.
