Korean Defense Blogger Bemil has shared this video on the crash of a KAI MUH-1 Marineon (an amphibious version of the KUH-1 Surion for Marine Corps use) yesterday in Pohang, South Korea.
It appears that the main rotor was detached from the helicopter while it tries to gain altitude, making the helicopter crash while flying just 10 meters off the ground. 5 occupants were killed while 1 was seriously injured as the helicopter burst into flames after crashing.
The name "Marineon" came from combining the words "Marine" and "Surion".
