OC Germany sent him to the Deutche Bahn train drivers school.
As I remember CC's own account:
The full and unredacted account said that when the AOC heard of the incident he telephoned the Fassberg Station Commander and said an investigation (possibly a Summary of Evidence) be undertaken with a view to a court martial. He was less than happy when the Station Commander replied that he had already taken action and given summary punishment, so that the matter had been dealt with. AOC asked what punishment had been given and was even less happy at the response "Well Sir, I told CC that I wouldn't have any of my officers doing a job for which they were not qualified and sent him to the Station shunting yard for a week".
CC's first court martial came later following the loss of an aircraft in the four-ship he was leading and he was given the traditional punishment posting to tow targets at Sylt, so the AOC may have got his revenge after all.
CC is much more respectable these days and lives in New Zealand.
