Eleven people were rescued after an airboat capsized off the Outer Banks on Wednesday, according to the U.S. Coast Guard.

A Dare County, North Carolina, dispatcher alerted Coast Guard Sector North Carolina around 10:15 a.m. that the 20-foot air-propeller-powered boat capsized about half of a mile west of Oregon Inlet, the Coast Guard said in a statement. The Coast Guard sent two response boats and a helicopter.

One person was pinned under the airboat and may have suffered a chest and head injury, the statement said. Oregon Inlet rescue boat crews pulled that person from the water and they were flown to a hospital. Coast Guard crews pulled the remaining 10 people from the water, including two people who were reported to have serious injuries.
