To be honest I find it quite worrying ! If an experienced pilot with one of the "worlds best airlines" can make such a mighty error on the ground what chance in the air where he can't apply the bakes? This is bound to affect his no claims bonus.
This 747 was still in a hangar at JNB when I was down there 6 weeks ago. Heading back this weekend and will be interested to see if she has been repaired and moved on.
