Say again; if they are making these claims then they are not reliable sources. Look, think about it. If this information is so classified, why on earth are they telling you about it?. Classified means classified, it means that access to the information in question is severely restricted. If the performance of the SR-71 or the CVNs was really so much greater than the released information states, then that is so highly classified, its way beyond top secret, its up in the compartmentalized information sector. Up there, reading people into a specific information compartment is a very serious business and people who get read into a specific compartment are subject to severe penalties if they even admit that compartment exists. And yet you are claiming that these same people blabbed the contents to you.
This is what would really happen if the people in question really had access to genuine information. The powers that be would be looking at your post about the SR-71 this morning and picking up telephones. By lunchtime they would be in touch with your internet provider with a warrant and get your personal information. By mid-afternoon two things wil have happened. One is that they will have pulled the files of everybody who has been read into that specific compartment and see which one of them has been in contact with you. Secondly, you will have been visited by the guys in sunglasses who drive black Suburbans and invited to assist them in their inquiries. When you ask "am I being arrested" the answer will be "yes". You and everybody on the clearance list will be interviewed in great depth over a prolonged period. Then, the people who blabbed the information to you will be charged and go to Leavenworth for a long time. You'll be given a talking-to you will never forget. Your name will also go onto a flag list and you'll find it very difficult to get a job with any Federal or State agency.
That's secret information. And you just told Calbear, who I've always thought to have been in the employ of the Russians. Expect the goons to come round: 3-ish okay?
Although hopefully it means Tom Clancy (used to write some good novels, then got a bit weird) will be arrested and beheaded in Time Square. Recall meeting one of his 'moles' grilling British officers for a new project.
