Interesting Post - Good memories
Post #312 by "Good memories" previously raised a similar focus on the cause. The email source is thought to be an active pilot who doesn't follow internet forums. Maybe we are closely circling around the actual events.
These types of post get to be massive in size and a little hard to follow. Some argue let's just wait for the "official" report but that would take all the fun out of it. But more importantly there is significant educational value in many of the well thought out and insightful post.
I think it is the nature of pilots to want to troubleshoot problems real time. When flying, you don't have the luxury to wait for the "official report."
