A hearing is scheduled to begin today for the two U.S. Pilots who took "go pills" containing amphetamines and mistakenly killed Canadian troops last year in Afganistan.

The hearing is to decide whether the pilots should face a court martial. "At issue is whether Air National Guard pilots Majs. Harry Schmidt and William Umbach are criminals or military men who made a tragic error while on duty in the Afghan war. The two face charges of manslaughter, assault and dereliction of duty -- which could bring up to 64 years prison time -- for dropping a 500-pound bomb on a Canadian military unit."

Lawyers for the pilots have said the mens' judgment may have been impaired by their usage of the amphetamine "go pills" given to them by the Air Force to combat fatigue on their missions. We wrote about this aspect of the case here.

Update: The lawyers rapped the Government hard at the hearing.
