In ufology, a USO is an Unidentified Submerged Object, which is really a UFO spotted traveling under water.
Most sightings of USOs have been by people while at sea, especially naval personnel. But less common sighting involve USOs emerging from or entering inland bodies of water such as lakes and rivers. The eyewitness accounts of USOs entering and exiting water describe the undertaking as seamless and virtually effortless on the part of the craft, which neither slows down nor compensates in any way when passing form one medium to the next.
Because USOs exhibit the ability to travel through both air and water, they are referred to as being "transmedium craft."
The seaman looked down from the rail of the ship and saw a large shape moving quickly through the ocean waters below, and so he at first thought he was seeing a strange-shaped whale. But then when it *swam* up out of the water and into the air, covered with lights, and zoomed off into the clouds, that's when he realized he had just seen a USO.
In ufology, a term for any "other-worldly" metals, alloys, substances, and artifacts allegedly retrieved by military and intelligence agencies from crashed UFOs. Once retrieved, the materials get stored in undisclosed warehouses and held for top secret scientific study. The efforts to covertly gather, store, and study such materials is believed to have been going on since the 1947 Roswell Incident. It is further alleged that various civilian-run contractors have been routinely executing "crash retrievals" upon the wreckages of downed UFOs for decades now, and have amassed multiple warehouses of these materials. The term "crash retrieval" will typically be used in the same conversation as the term "exotic materials."
The most famous example of an alleged exotic material in UFO lore is probably the "memory metal" which witnesses at Roswell claim littered the debris field of the 1947 crash.
The most important allegation about exotic materials is that supposedly most post-WWII technological breakthroughs --including transistors, semiconductors, microchips, motherboards, photovoltaic solar panels, night vision, heat vision, stealth technology, nano-tech, and the whole US space program-- would not have been possible without decades of access by secrecy-bound research scientists to these untold hauls of crash-retrieved items. The issuing of secret patents early on in the research process of these materials is the true incentive for military contractors to engage in the research.
Government scientists are secretly studying a vast collection of exotic materials that have been retrieved from crashed UFOs over the past 80 years. With each new exotic material they find, these researchers hope to unlock the hidden properties of these items, and derive practical applications (both military and commercial) from their findings.
A Confidential Human Source, or CHS, is an informant who covertly provides information to law enforcement about criminals and their activities. Their names are withheld from official law enforcement reports and documents to protect their identities.
Some critics of law enforcement claim that some instances of an alleged CHS are a mere fabrication, and there never was an actual human who provided the information. These critics claim that in such cases where the law enforcement agents fabricated the CHS did so as justification for a search warrant or other similar legalities of an investigation.
The FBI claimed they were told about the drug ring by a Confidential Human Source.
