The first time I ever jumpseated was many years ago on an ABX DC-8. A CA, an FO, and an over 60 PFE wearing four stripes. The dynamic was beautiful. It was good to see a CA, the PIC, asking for concurrence from from a well seasoned flyer. Perhaps, that is the way it was meant to be.
I wish I could look over my shoulder to an old sage every now an then.
