The said Captain, who is a really great guy, made a serious error in judgement and may have to live with the consequences of it for the rest of his life.
He had a hot mike and when they tried to contact the engineer to find out if the chocks were in so that they could release the park brake due to the A340 having notoriously high brake temperatures from a landing and taxi in, they received no response. The Captain then made an unacceptable general comment using the "K" word and the engineer happened to be on the headset when the comment was made.
It is interesting to note that the third pilot was Indian.
The lesson to be learned here is that many white South Africans still freely use the "K" word in general discussion and it is time to eliminate this word and this attitude from our social banter as it is offensive and degrading and is a poor representation of the individuals using it. Next time you hear someone using this word, have the balls to stand up to them and tell them that it is not on.
