Coast Guard releases radio transmissions from fatal duck boat crash in Philadelphia

An unidentified man can be heard yelling for a boat to watch out on recordings of radio communications from a fatal duck boat crash in Philadelphia.

The audio released Friday was taken from the emergency channel recorded by the Coast Guard on July 7 when a duck boat carrying 37 people became disabled in the Delaware River and was struck by a barge being pushed by a tug. The duck boat capsized and sank, killing two Hungarian tourists.

A few minutes after the crash, the tug boat is heard telling the Coast Guard: "We are the ones that, I guess, capsized the duck boat. We're on scene, but we do have a barge along side so there's not too, too much we can do."

The Coast Guard then told the tug's crew to throw lifejackets to survivors.

The investigation into the accident continues.
