Just found this... searching "satellite", "secure", and "carrier" turn up interesting results...
Also:
"threatcon" returns mostly military/government messages
"hijack" returns WTC witness messages
Something interesting here... I searched the word "success", hoping to find something from the hijackers or Al-Qaeda operatives in the U.S., and found a few messages from one person. The field that's marked "Msg ID" seems to be the capcodes of the recipient pagers. I know it's a lot of work, but the ability to search by capcode would definitely be interesting. Finding one compelling message, followed by a search using the corresponding capcode would allow you to effectively lock on to one pager belonging to a government official, reporter, possibly even an al Qaeda operative. Once you've done that, you won't have to sort through all of the other irrelevant messages and find something pertinent.
