Mike - I first met Pete Frame on a DO's course in Portsmouth in '64 when this photo was taken
and then he was the COD pilot on Ark when I was there in 65/66.
You may be interested in this PPRuNe thread which mentions Pete (posts 6 and 17) the latter being a post by one of his children:

That thread is how I found out he had crossed the bar but I don't know the circumstances. Maybe a PM to his offspring if you wanted to know more?
