PHILADELPHIA (AP) -- A Philadelphia sightseeing operation whose amphibious boat was struck by a barge and sank says it followed safety recommendations.
Thirty-seven people were dumped into the Delaware River on Wednesday when a barge collided with the duck boat, which looks like a boat with wheels and can travel on roads and in water. Two people are missing.
Federal regulators recommended duck boats increase buoyancy after one sank in Hot Springs, Ark., in 1999.
A spokeswoman for the Philadelphia Ride the Ducks operation says its boats added buoyancy. Spokeswoman Sharla Feldscher said Thursday all National Transportation Safety Board modification requests were followed.
The Norcross, Ga., company that owns Ride the Ducks has suspended operations in San Francisco, Atlanta, Newport, Ky., and Branson, Mo. A Seattle operation is independently owned and remains open.
