Hundreds were visiting Sapelo Island in Georgia for a fall festival spotlighting the history and culture of its tiny Gullah-Geechee community.

Eyewitness video from the scene of a deadly gangway collapse at a dock in Georgia shows bystanders jumping into action after 20 people plunged into the water off Sapelo Island.

The metal gangway where dozens of people waited to board a ferry boat snapped and sent dozens plunging into the water.

"It took seconds." White's family was among hundreds visiting the isolated Georgia barrier island Saturday for a fall festival spotlighting the history and culture of its tiny Gullah-Geechee community of Black slave descendants.

Eyewitness video captured the frenzied moments after a Georgia ferry dock walkway collapsed Saturday, killing seven people. The video, published Monday by The Associated Press, shows people clinging to the broken walkway to keep themselves out of the water.
