I saw a ************************* pilot yesterday at ORD enter security in terminal 2 through the exit side. There were alot of airline employees going through security on the normal right hand side at the employee line. I was exiting the airport and coming out of terminal two. He had his flight case and didn't even make eye contact with me. I thought this weird to see someone entering over on the left side. Never seen it before. He had a white badge that said *************************s in blue on it. I got a good look at badge. Some old tall skinny grey hair dork with glasses.
