FYI - the Defense Science Board has posted a revised version of their February report. The April 2008 revised version of "The Defense Science Board Permanent Task Force on Nuclear Weapons Surety: Report on the Unauthorized Movement of Nuclear Weapons" is available directly at
or from their main reports page http://www.acq.osd.mil/dsb/reports.htm
According to the revised version, they had completed the information gathering in December 2007 but in "April 2008 a data error was discovered" and the report was revised accordingly. "Specifically, report Section III: Nuclear Enterprise Focus was updated to reflect that the Strategic Air Command tanker force was reassigned to the Air Mobility Command (vice Military Airlift Command)."
