The Coast Guard has released audio of the initial radio call from the captain of the Disco Volante on July 26 in Cape Cod Canal. At the end of the audio, the watchstander says, "be advised, there are units en route at this time."

Twelve people, nine children and three adults, were taken out of the water during the incident. One 8-year-old was flown from the scene to Children's Hospital in Boston after being trapped beneath the boat. His condition has not been released.
