After Dr. Grant Smith pleaded not guilty on Monday to charges that he watched child pornography on a plane, his father talked exclusively to RadarOnline.com about the scandal that has rocked their family.

"I am about shocked the charges that are brought against him," the University of Utah science professor's dad, Bruce Smith, told us.

As RadarOnline.com previously reported, Dr. Smith was arrested on a charge of child pornography possession Saturday by authorities in Massachusetts immediately after his Utah-to-Boston flight landed at Logan Airport. He was held in lieu of $75,000 cash bail Monday.
