A Kansas man who plotted a suicide bomb attack aimed at causing "maximum carnage" at a Wichita airport has been sentenced to 20 years in prison.

Terry L. Loewen apologized Monday during his sentencing to his family for the pain he had caused them.

The 60-year-old Wichita man pleaded guilty in June to attempting to use a weapon of mass destruction. U.S. District Judge Monti Belot imposed the proposed sentence that came with the plea deal.

The avionics technician was arrested during an undercover operation in December 2013 when he tried to bring a van filled with inert explosives onto the tarmac at Mid-Continent Airport.

He came to the FBI's attention when he became a Facebook friend of an individual who regularly posted information supporting violent jihad, or holy war.
