Speaking as a non-expert witness but ... in 1966~74, I was living in the Pretoria suburb of Waterkloof, just the other side of the hill from Waterkloof airbase. Also, we attended many air displays and memorial services at the base's special memorial chapel as my dad was RAF and made many SAAF friends and joined the SAAFA. So I saw these machines overhead for many years in my teens.
I do't think that there were any Canberras or Meteors around but Impala and Buccaneers were all over the place all the time. On the balance of probabilities - they must score highly!
