I couldn't care less if you believe that I am actually what I say I am.
'Belief' does not come into it.
In Britain, people in your line of work have to sign the Official Secrets Act.
Which means they are not allowed to say a thing about what they do to anyone, even after they have finished working on the project.
The penalties for breaking the Act range from Prison & Fines down to, at the very least, total loss of professional livelihood & being blacklisted for the rest of their lives.
It is a VERY serious business.
Now, I do not know exactly how they go about it in America, but I doubt the penalties are much less severe.
So, yet again, I state that the simple Fact that you are here, on an INTERNET CONSPIRACY FORUM, openly bragging about what you do, where you live etc, & saying things like 'GPS does not require satellites' can ONLY mean that you are NOT a real missile engineer.
The idea is RIDICULOUS.
So stop your bullshit, engy baby, & get back to fixing the sliding canopy above Doctor Evil's Volcano Lair, or whatever the hell fantasy nonsense it is you get up to in your imagination...
