Dan Sherman joined the Air Force in 1982 to be what was then called Security Police (now known as Security Forces). While serving in Korea in 1984, he met another airman who told him about how great it was to be in Electronic Intelligence (ELINT). The man spoke about it so often, it convinced Sherman ELINT was where he wanted to be as well. Sherman was unhappy with being in Security and often told others if he couldn't cross-train to the ELINT career field, he would get out entirely. His peers told him his job in security was a critically manned field and his chances of cross-training out were zero.
As luck would have in Sherman was approved to train into ELINT, analyzing electromagnetic energy for intelligence value. He went to tech school in 1990 and was stationed at Offutt Air Force Base in Nebraska. While he liked the job, he wasn't thrilled with Offutt. He wanted to get back to Korea, and told his peers as much, even going so far as to say he wouldn't re-enlist if he didn't get orders there. His luck held again. A month later, he had the orders in hand.
He was enjoying his new career field and in 1992 was sent to Fort Meade, Maryland to train in an intermediate-level ELINT course at the National Security Agency (NSA) building there. His first day in town, he was ordered to report to the NSA for what he thought would be a quick introduction. His life was about to change forever.
According to his book "Above Black: Project Preserve Destiny," Sherman was indoctrinated into an above Top Secret-level program involving what the Air Force called "Greys." Grey are purported to be extra-terrestrial beings first encountered by the United States in 1947. Since the early 1960's, it was revealed to Sherman, the U.S. government had been working on a way to communicate with the Greys. That's where he came in. His mother was "visited by aliens" before he was born. She was the subject of genetic manipulation, the result would be bearing a child who could be more receptive to the way the Greys communicate, receiving transmissions and passing them on.
The Air Force had been waiting for Sherman his entire life. He was part of a new communication plan just coming to fruition. His mother was not supposed to be able to have children. When she was pregnant, little Dan Sherman was not supposed to survive for long. All through his life, people had been telling him how great the Air Force life was, making that life seem to be his own destiny. Now, here Sherman sat, ready to be what the USAF called an "Intuitive Communicator."
After his regular training courses at the NSA, Dan was taken to an unknown location in a blue Air Force van with blacked out windows. He was given two pills and instructed on how to move waves on electronic screens with his mind. Once he was proficient, he was released and given new orders, now as part of Project Preserve Destiny, or PPD.
His first PPD base established what his life would become. Though he no longer took the pills, he and another airman would sit in a communications van for their shift. Sherman would receive the communication, which included his identifier, 118, a five-digit code, and then what Sherman came to believe were latitude and longitude coordinates. His first handler was a Grey Sherman nicknamed "Spock."
One day during communication, something startled Sherman and he reached a new "plane." The alien asked Sherman if this was intentional. When Sherman said it wasn't, the alien ended the conversation. Sherman would try for months to repeat the situation. Eventually, he was able to, and asked "Spock" some questions about their race and how they were communicating. Sherman's command was apparently unable to monitor his communications with the Greys, so he was free to ask what he wanted. But after this second meeting, Spock never returned and Sherman was transferred to a new PPD base.
His role at this second base was very similar, but this time "Spock" was gone forever. His new counterpart (whom Sherman nicknamed "Bones") was more conversational and forthcoming. Sherman asked about how the beings age, procreate, travel through space, and if they had souls. Here are a few more answers from the Greys to questions posed by Sherman:
"You question answers itself."
They don't travel through time but around time and from time to time.
"Any entity that realizes its existence has intellect and therefore must have a soul."
4. Previous visits
They've been visiting Earth for a "very long time," because its much easier to visit the past than it is today. They've contributed to the culture and technology of some civilizations.
Sherman believes they interbred with Humans (whom the Greys call "water vessels"), most likely the Basque people of the Pyrenees region of Spain, whose language is completely unrelated to any other and whose genetic makeup is different from most humans.
6. Other Aliens
There are many.
They do it, just different from the way humans do.
They do that too.
9. Life Span
They don't see time the same way humans do, but they live approximately the same span.
Earth's sun is unique and one day we will learn to use the same energy on a smaller scale.
When Sherman asked "Bones" about Project Preserve Destiny, the Grey abruptly ended their ongoing discussions. Shortly after that, the nature of the "comms" between the Air Force and the Greys changed. Sherman started receiving what he calls "abduction data," complete with dates, geographic information, potential for recall (reabduction), and a 1-100 "pain scale." Rememberign some of the coordinates, he traced some sites to the Florida panhandle, Upstate New York, and rural Wisconsin.
Increasingly isolated from the outside world, Sherman began to grow increasingly frustrated with his PPD work. He wanted to go back to ELINT or to get out entirely. The response from his command was that he could not only never go back to ELINT, but he could never separate from the Air Force now that he was part of PPD. He did the only thing he knew to do. In the book, Sherman says "the way I obtained my discharge is not a secret. Anyone can go back and see the reason emblazoned on my discharge papers. But certain self-incrimination legalities keep me from discussing it here."
According an interview with Sherman on the website Exopolitics, which (*sigh*) studies the communications of aliens with humans, Sherman's twelve years of Air Force service were exemplary. He earned an Air Force Commendation Medal, as well as three Air Force Achievement Medals and four Outstanding Unit Awards. he also served in the Persian Gulf War.
Sherman concluded his story with this:
I only wish I could have continued an otherwise wonderful career of which I was extremely proud. I miss serving my country and being part of the most sophisticated and well-trained military in the world.
