• On 29 May 2001 a ROK Army CH-47D installing a sculpture onto Olympic Bridge in Seoul, South Korea failed to unlatch the sculpture. The helicopter's rotors struck the monument; then the fuselage hit and broke into two. One section crashed onto the bridge in flames and the other fell into the river. All three crew members on board died.
