bosstrabs Im not slapping down Wally. I hadn’t seen that graph until he posted it. I’m going with the cockpit struggle for now, very unusual for a plane to dive like that due to engine or hydraulic failure, especially feom cruise altitude.
I studied history and warfare, Dave and I’ve been an aviation enthusiast since my cousin brought me to his ATC tower in ’82. Its about all I know, hence my non participation in threads I know nothing about. 🤷♂️
