Its for pulling crap like this why I would never fly on a Kolean airline.
Their English is atrocious - we have all heard them around the region. Closely followed by the Mainland pilots who can't even say their own call sign if it goes into 4-Digits.
And at the bottom of the steaming pile of bad spoken English are the Australians. Who ironically are the ones going for the $20K per month China contracts.
Something about holes lining up.....
