I have fond memories of sitting in a field under the 09L approach with a BA Engineering colleague and a portable B&K recorder doing noise spectrum analyses soon after AFR started A300 ops to Heathrow in 1974.
I, like many others went to LHR to see the inaugural flight land from Paris on 28R (if memory serves) very excited to see this new beast, only to be brought down to earth by some nonchalant spectator up on the Queens Building who didn't see the fuss "as it had landed yesterday on a test flight" to make sure all went smoothly on the day.
I always found the A300 a nice aircraft to fly on and due to chance and circumstance flew on most of the airlines that operated them save a few. Air Afrique was my favourite C/S on the A300.
