My understanding was that after he was told to depart the pattern at DCA he purchased the CAPT program from ERAU and was encouraged to leave DAL because of the conflict of interest. From what my wife tells me, he burned any remaining goodwill at the airline with his childish actions against Doug. Basically he violated rule #1: leave your baggage at home.
That's kind of what I heard.
When I was doing my domestic IOE, the check pilot and I had dinner and filled me in on a lot of interesting details about his exit.
Apparently, much to my surprise, his antics against JC and myself pissed off a lot of people. A LOT.
(edit: I'll leave the rest of the story for a meet 'n greet or NJC because I have a lot of juicy details that I don't necessarily want showing up on Google!
Needless to say, he's the only person in my 39 years that I haven't been able to fully do the "right thing" by finding peace with and forgiving. I'm working on it though, but it's hard.
Can't believe a fellow aviator would try to use his influence to have me fired to further his business interests. FAIL.
