Three soldiers of the U.S. Army’s Golden Knights parachute demonstration team were injured during a jump in the early morning hours on Tuesday, February 12. According to the Miami Herald, the soldiers were conducting a nighttime jump around 4 a.m. near Homestead Air Reserve Base when the accident occurred. Local emergency response crews from Miami-Dade Fire Rescue responded to the incident, and the soldiers were transported to a local trauma center via helicopter, according to CBS. The Army is withholding the names of those involved and their current medical condition until a next of kin notification has been made.

“The soldiers are all members of the U.S. Army Parachute Team, the Golden Knights, and were participating in a routine night training operation,” Army Recruiting Command public affairs wrote in a statement. “They are being treated at Jackson Memorial Hospital’s Ryder Trauma Center in Miami, Florida. The incident is under investigation at this time.”

The Golden Knights are the Army’s parachute demonstration team, similar to the U.S. Air Force’s Thunderbirds or the U.S. Navy’s Blue Angels. The majority of the soldiers assigned to the Golden Knights belong to the Army Recruiting Command and are typically based at Fort Bragg, North Carolina. According to the Miami Herald, the team works from Homestead ARB in South Florida during the winter months. The group often performs during airshows and before the beginning of sporting events, often parachuting from an aircraft onto the field.
