FV: the "fly spot" episode was after Rongotai.
A sequel to the Rongotai accident you may not know of is that the crew sent out to take the a/c back damn near did the same thing at Ohakea. During a test flight prior to returning to UK they did a roller on 33 at Ohakea and left rubber on the stones just short of the runway lip !.
There are still several KAa's lovingly preserved by museums. To the delight of the enthusiasts they are allowed to venture on the main trunk line occasionally.
