NTSB member wants on-the-job naps considered

US National Transportation Safety Board member Mark Rosekind announced on-the-job naps should be considered as part of a plan to address fatigue by air traffic controllers, pilots and others who work overnight shifts (AP, 25-Apr-2011). Mr Rosekind is a fatigue expert who formerly worked for NASA and directed a sleep research centre at Stanford University. He claims short naps refresh workers suffering fatigue and help them remain alert while on duty.
