Hi all, I am currently doing a Year 12/HSC engineering assignment on aeronautical engineering. I need to construct a timeline on a specific component from a plane that I am studying. My component is the aft pressure bulkhead, this is because it is in relation to the plane I am investigating; JAL 123. So, could someone be able to help me and either give me a detailed response on the history of the aft pressure bulkhead (in general) or at least guide me to somewhere that can provide me with this information. Please and Thank You.
