A federal judge is encouraging government lawyers to review what he calls “substantial” blacked-out material given to defense attorneys for a man accused of plotting a suicide bombing at Wichita’s airport.

U.S. District Judge Monti Belot told attorneys Monday he wants to move along as rapidly as possible the case of Terry Loewen, an avionics technician jailed on terrorism-related charges. Belot gave prosecutors 30 days to respond to a defense letter outlining evidence it contends should be disclosed.

Loewen was arrested Dec. 13 after allegedly trying to bring inert explosives onto the tarmac at the airport, where he worked.

He has pleaded not guilty to attempting to use a weapon of mass destruction, attempting to use an explosive device to damage property and attempting to give material support to al-Qaida.
