This is a breakoff from the Roswell thread, where it was claimed that TOP SECRET (TS) was "too low a classification" for anything to do with any possible "coverup" of an extraterrestial craft crashing at Roswell in 1947.
I maintain that TS
IS the top level of classification for the US military, and that if any coverup did take place at Roswell (which I personally dispute), the information would still have been classified under the normal conventions (Secret, TS, etc) and again, within the normal conventions, have a codeword (SCI / SAP) applied.
I invite neverfly to have a look at this:
http://www.fas.org/irp/doddir/dod/5200-1r/index.html
That's DoD 5200.1-R, INFORMATION SECURITY PROGRAMME. The Bible regarding security classifications.
I would ask neverfly to point out anywhere in that document it refers to a classification higher than TS. I'd expand that request to point out an official US government document that refers to a classification higher than TS.
Mods, request you move the relevent posts from the Roswell thread to this one.
