The Russian Mil Mi-26 helicopter is the largest in the world, able to lift up to 20 tons (the same cargo capacity as a Lockheed C-130 transport aircraft) or over 100 passengers. It's almost as big as a Boeing 737 airliner.
An Mi-26 was coming in to land on the Yamal peninsula in Russia a few days ago when something went wrong.
Looking at the fragments of its massive eight-bladed rotor flying around, I'm glad I wasn't anywhere nearby! There's no word on casualties, but it landed tail-down, and the fuselage looks relatively intact, so I hope those inside managed to get away with only minor injuries.
