Massachusetts State Police say 47-year-old Grant Smith was sitting in first class Saturday afternoon when a fellow passenger saw the pornographic images onSmith's laptop and alerted the flight crew.
When the Delta flight landed at Boston Logan International Airport just after 4pm, troopers interviewed Smith and subsequently arrested him.
He has been charged with possession of child pornography, and police say additional charges could follow. His bail is set at $15,000. He is scheduled to be arraigned Monday.
Smith was in police custody Saturday night and couldn't immediately be reached for comment.
