A member of a U.S. Navy SEAL skydiving group was killed in a parachuting accident on Sunday while performing in an aerial exhibition as part of the annual Fleet Week Festival in New York Harbor, a Navy official said. The skydiver, whose identity was being withheld pending notification of relatives, plunged to his death when his parachute failed to open, Rear Admiral Jack Scorby told reporters outside the New Jersey hospital where the man was pronounced dead.
