The CAA didn't exist until 10 years later ie 1975.
Thank you chevron (I wondered who'd spot that one first, Wilson! ;-). Which perhaps makes it more likely that our man was an AAIB Inspector who had discovered the cause of the crash within hours of it happening, and hence the AAIB involvement was from the very start of the investigation. That in turn could have led to the misunderstanding that the formal accident investigation was carried out by them. It was not of course, it was carried out by a BoI.
Hope that answers your query Leon. Again, can anyone help us trace that 1965 BoI report?
