An "insider source" is literally someone who is "inside" a program. You seem to be arguing the best "insider source" is someone "outside "the program.
Persons inside a program may or may not have access to confidential, classified, or proprietary information. Those that do have access to that information are well informed as to what they can and cannot talk about or disclose. Many members of this forum have been inside various programs and talk about them. For example,
@F119Doctor and
@mkellytx were "inside" different programs and talk about them while mindful of the boundaries of what they can and cannot talk about.
It seems that there is a widespread misconception that if a program is not talked about much by DoD components that it is classified, or all aspects of it are classified. Nothing could be farther from the truth. Using F/A-XX as an example, the volume of unclassified, reachable information on this program is staggering. I have obtained records totaling over 2GB simply by asking for them. In some cases DoD has.... erroneously claimed records are classified - because they share this misconception. Information cannot be classified by the wave of a magic wand or just a statement by a delegated "classification authority". For something to be classified requires an extensive paper trail, which often does not exist. In some cases like information disclosed to Congress there may be both classified and unclassified versions.
But lately I see that a lot of people are not actually asking for this information from DoD, etc. and instead just make their own claims of classification, secrecy, etc. and create fantasies or speculation about these programs that have no basis in fact.
This was not always the case. In the past - the Before Time - forum members regularly did their own independent research and shared it with others. Documents from DTIC, from various archives, etc. Members shared expertise and enthusiastically engaged in fact-based conversations. They did not engage in practices like attempting to annoy or attack a fellow member until the member did research on their behalf or provided information.
I prefer the Before Time.
For those who are interested in the F/A-XX program, I would recommend they ask the relevant DoD components and Congress for the specific information they are interested in, particularly records that are known to have been disclosed. If someone does this they will find that the program is very different than what has been discussed in the bulk of this thread.
