Thanks for that information about G-AIPS Auster J/4 from Denham Flying Club. I wanted to give an idea of what the 5 participating aircraft from Airways Aero Association might have looked like on their pre-departure from Denham to Heston on the 9th June 1951, so this could have been a similar picture. Perhaps an old AAA member or someone who used to fly from Denham can give an idea of which Auster flew on this day, it could have conceivably even been G-AIPS rather than an Aiglet Trainer since I believe that these came into service with the AAA in 1952 from what I have seen from G-INFO so far. Pity that no earlier BOAC member has been able to add to this post, although they would of course now be at least over 75 year old and I was a youth of only 12 years then, so I am slowly getting ancient too
