Wow so what everyone is wanting to know is can a guy, who's never flown the a/c..Has no experience/knowledge of any systems, limitations of that a/c....has absolutely zero training on the handling characteristics of the a/c.. Sit in the right seat.. ?
Hell why not just have him sit in the back, that's about as much help he'd be in an emergency...
And people wonder why professional 121 pilots look down upon rag tag 91 outfits
