The captain of a tourist "duck boat" that sank near Branson, Missouri July 19 briefed his passengers about how to use life jackets before the amphibious vehicle entered the water, according to National Transportation Safety Board (NTSB) technicians, who’ve been studying a recording from “Stretch Boat 7.” Seventeen people died when the amphibious vehicle sank in Table Rock Lake during a severe storm.
The NTSB has concluded an initial review of information gathered from the vehicle’s digital video recorder camera system. An SD card and a removable hard drive from the system were recovered by divers before the duck boat was salvaged.
