Hi John.
Nearest I’ve ever got to the aviation industry was a tour of the Rolls Royce engine plant at Derby last year! The technology on show there is a sight to behold.
Experience in cobbling together aluminium sheet fabrications probably comes from my motorcycle road racing exploits in the not too distant past.
For my sins I am a Civil Engineer in a specialised sector of the construction industry. Now semi retired and delivering training courses as and when. Or I was pre-lockdown....
Best wishes
