My Dear Capt.,
You, first, Make the misunderstanding that he even cares to be professional in the sence that you are. He is a criminal and is probably considered a professional among his peers. The thrill of "can he pull it off" is so great, like drugs. In his mind he "punked" us all, if he had make it for a year, he likely would have had to up the stakes, and maybe done some other real bad actual harm to the planes. I have connections to fake papers, and two or three phone calls, lets call that a cursory check, and he certainly could do that or he wouldn't be have been there, it needs to be looked into down the line as far as possible, maybe they find terrorist connections, and some hidden project he was to do but fell thru at the time so he pushed the job so he could stay.... Who knows, but open your head beyond yourself and think out of your box. I mean no insults what so ever, I trust my pilot to be a professional, and have the client's interest ahead of your own, I truely only want to help your think process, I applaude you and all other pilots, you do something I can't, but need.
