Welcome to the forum!
When I was still in, I knew a captain for UAL (originally Pan Am) who was an elder in the Agoura/Thousand Oaks area of CA. I believe his name was Jim as well, but I can't recall his last name. It has been 20+ years since I saw him (I've been out since the mid-90's), but I remember him being a nice fellow. I can't imagine there were many UAL captains that were JW's. He has been retired for 20+ years, so I imagine he is in his 80's now. I believe he retired a year or two after the Pan Am merger...he flew 747's in the Pacific.
