Documents newly found at the National Archives show that in the weeks before the 9/11 Commission issued a subpoena for tapes of events at the Northeast Air Defense Sector (NEADS) on the day of the attacks, it told the military not to send some or all of them to the commission. The documents are internal commission e-mails and a memo, as well as communications between the commission and the military. They were found at the National Archives by History Commons contributor Erik Larson (a.k.a. paxvector) and posted to the 9/11 Document Archive at Scribd.
