A Russian military helicopter has crashed at an air show before thousands of spectators, killing one crew member and injuring another.
The commander of the Mi-28 helicopter was killed after the aircraft crashed during an aerobatic display at the August 2 air show in the Russian region of Ryazan, 200 kilometers southeast of Moscow.
"The commander has died, the second pilot is alive. According to the second pilot, equipment failure caused the accident," the head of the Russian Air Forces, Colonel General Viktor Bondarev, was quoted by the RIA Novosti news agency as saying.
The air show, Aviadarts, featured Russian Air Force plane and helicopter crews competing to fulfill timed assignments.
No spectators were injured, and the event was suspended for the day following the accident.
Russia's air force has used the Soviet-designed Mi-28 since the mid-2000s, and the aircraft is also exported to numerous countries, including Iraq.
Bondarev has grounded the country's Mi-28 fleet pending an investigation.
