ExpressJet Airlines first officer Michael Roberts was chosen for the X-ray scan Friday at Memphis International Airport. The Houston-based pilot says he also refused a pat-down and went home.
The 35-year-old Roberts told The Commercial Appeal newspaper he wants to go to work and not be "harassed or molested without cause."
Transportation Safety Administration spokesman Jon Allen says a person was turned away after refusing to follow federal security procedures but declined to say if it was Roberts, citing privacy considerations.
Roberts says he has safety concerns, but called TSA a "make-work" program that doesn't make travel safer.
