This is crazy. Not sure about the source.
From 3AM on Wednesday November 25, 2009, until 3AM the following day (US east coast time), WikiLeaks released half a million US national text pager intercepts. The intercepts cover a 24 hour period surrounding the September 11, 2001 attacks in New York and Washington.
The messages were broadcasted "live" to the global community — sychronized to the time of day they were sent. The first message was from 3AM September 11, 2001, five hours before the first attack, and the last, 24 hours later.
