On 26 May 1997, three Ukrainian Air Force Su-27 aircraft of the 831st Fighter Aviation Regiment collided with each other on the ground at Mirgorod Air Base. The incident became known as the "Mirgorod Pyramid".
During a previous flight on 25 May 1997, the pilot of the aircraft had left the starboard engine throttle in the afterburner position. This was not noticed when the aircraft was started up the next morning, resulting in the aircraft immediately veering to the left. 68 Red first hit the Su-27 07 Red, before also crashing into the Su-27UB 72 Red.
While the aircraft were significantly damaged, there were no injuries. The Su-27 07 Red was later decommissioned and transferred in 2001 to the Ukrainian Air Force Museum in Vinnitsa. The other two aircraft were repaired and returned to service.
A large scale inquiry was conducted by the Ukrainian Air Force. As a result of admitting their failures in operational protocol, the pilots were permitted to remain in the air force, albeit with strict penalties and requirement to compensate for material damage.
