Friendly fire deaths linked to US pilots 'on speed'
   'American pilots in Afghanistan, blamed for a series of "friendly fire"
   incidents and devastating erroneous attacks on innocent civilians, were
   routinely provided with amphetamines to tackle fatigue and help them
   fly longer hours. Pilots were allowed to "self-regulate" their own
   doses and kept the drugs in their cockpits ... Pilots who refused to
   take the drugs could be banned from taking part in a mission' (
   Independent )
