One Pilot Dead After Russian Military Helicopter Crashes During Air Show

One pilot died and another was injured after a Russian military helicopter crashed Sunday afternoon during an air show.

The surviving pilot said an equipment error caused the Mi-28 helicopter to fall out of the sky and burst into flames after hitting the ground in the Ryazan region, Reuters reported. The helicopter was a part of Sunday's International Army Games — an event during which the Kremlin shows off its military.

Here's a clip of the accident:

No spectators were injured in the accident as the show is conducted a safe distance from the audience, according to the Associated Press. However, Viktor Bondarev, Russia's air force chief, has called for an investigation and has grounded the military's Mi-28 fleet in the meantime.

Lieutenant Colonel Igor Butenko, the first pilot of the helicopter, died in the crash.

"There are situations when it's impossible to survive no matter how well-trained the pilot is," said Butenko's son, an air force academy cadet, according to the Associated Press.

The model of the helicopter that crashed is the same kind that's been sold to Iraq and Kenya, as well as other countries, the AP reported.

As Sunday's accident marked the seventh military accident this month for Russia, questions are mounting in regard to the military's safety standards and requirements.
