Footage released of deadly marine corps helicopter crash
South Korea's Marine Corps unveiled footage of Tuesday's helicopter crash in Pohang that killed five and left one seriously injured. The 10-second clip shows the vehicle crashing shortly after take-off... as its rotor blades fall off. The corps launched an official investigation committee... to figure out the exact cause of the accident. The MUH-1 chopper was exclusively developed for the Marines by Korea Aerospace Industries, which delivered four of them early this year. The original plan was to take 28 helicopters by 2023, but that could change depending on the result of the investigation.
