History

The Republic of Korea Air Force Black Eagles aerobatic team has operated in various occasions of national ceremonies and at international air shows.
The original display team was formed on October 1, 1953 and operated four F-51 Mustangs. In October, 1956 a new display team "T-33A Show Flight Team" was formed.

On October 1, 1959 a new display team was formed. This team was called the "Blue Sabre" and they flew four F-86 Sabre jet airplanes. This team was disbanded in 1966.

In 1967, a new display team "Black Eagles" was formed. It operated between 1966 through 1978 and flew seven Northrop F-5A Freedom Fighter airplanes.
1966~1969 used F-5A. 1970~1972 is interrupted the flight. 1973~1978 used RF-5A. In 1978, the team disorganized due to defense preparedness enhancement.

The full-time aerobatic team, Black Eagles, was re-established as full-time aerobatic team on December 12, 1994 and flew six Cessna A-37B Dragonfly airplanes. The Black Eagles team was disbanded after the 2007 ADEX 2007 and has been reformed upon the arrival of their new T-50 Golden Eagle aircraft which were scheduled to be delivered in 2010.
However, the Black Eagles reformed ahead of schedule in time to fly over Seoul on September 23, 2009 to commemorate the 60th anniversary of the Republic of Korea Air Force.

T-50 characteristic

The T-50B is the only supersonic advanced trainer jet equipped with both high-tech electronic devices and state of the art advanced avionics systems.
With the successful introduction of T-50 series(T-50, T-50B, TA-50, FA-50), the Republic of Korea has become the 12th nation in the world to produce supersonic aircraft using their own technology.

Black Eagles's T-50B is painted in yellow, white and black with eagle soars, and sleek curves showing the dynamics of eagles, giving a strong and aggressive feeling.
With pin-cameras installed at the cockpit and at the bottom of the aircraft, maneuver analysis and visual materials have become easier to be obtained.
T-50B aircraft also has visible lights on both sides of each wing tip which helps the pilots perform maneuvers and encourages audiences to enjoy the show.
The T-50B is equipped with an internal smoke generation system which creates a thick smoke trail. The T-50 is very fast, very slow enough and has best maneuverable characteristic with Fly-by-wire system(it is ideal for aerobatics jet).

Smoke

The thick smoke trails of Black Eagles aerobatic team are made by releasing diesel and oil into the exhaust nozzle; this mixture immediately oxidizes, leaving a white smoke trail. There are two smoke tanks in the aircraft, each designed to carry about 60 gallon of smoke oil. The Smoke system can control the quantity of oil released, so each aircraft can trail smoke for 7~20 minutes.

Accidents

• May 8, 1998 - During a training flight two of the team's planes collided in mid-air. One of the planes crashed killing the team leader of the Black Eagles. The other plane landed with minor damage.

• May 5, 2006 - Suwon Air Base, Korea -An A-37B flown by Captain Kim Do-hyun, 33, crashed onto far edge of the runway during an air show that was intended to celebrate Children's Day. Cpt. Kim's A-37B, along with another A-37B from the team, just finished engaging the "Opposing A-Roll" maneuver, but Cpt. Kim's plane failed to climb after the maneuver and ended up crashing the far southern side of the runway, 1.8 kilometers away from the crowds. Crowds ranging in thousands, including many children, witnessed the crash. Major Bae Duk-hwan later commented that "...the pilot could have escaped but held on to the flight controls until the end as he judged that the plane might crash into the stands. If the pilot had let go of the flight control stick, nobody would have known where the plane would crash." Cpt. Kim was buried with full military honours at the National Cemetery.
