I actually entered the competition!
The aircraft was G-APBE and it came to Newcastle on 21 May 1957.
I can’t remember much about the competition (Needless to say I didn’t win it!) except that when I applied I was sent one of those psychometric tests to fill in. You know the sort of thing – What thoughts go through your mind when you see a picture of a lighthouse,etc, etc. I filled it in but never heard any more. I often wonder what response I should have given to the lighthouse question!
I see that G-APBE still exists and belongs to a Mr. Woods.
