A secretive CIA office has been coordinating the retrieval of crashed UFOs around the world for decades, multiple sources told DailyMail.com. One source said that at least nine apparent 'non-human craft' have been recovered by the US government some wrecked from a crash, and two completely intact. Three sources briefed on those alleged top secret operations [said] that the Office of Global Access (OGA), a wing of the Central Intelligence Agency's Science and Technology Directorate, has played a central role since 2003 in orchestrating the collection of what could be alien spacecraft. 'There's at least nine vehicles. There were different circumstances for different ones,' one source briefed by UFO program insiders [said]. 'It has to do with the physical condition they're in. If it crashes, there's a lot of damage done. Others, two of them, are completely intact.' The source said the CIA has a 'system in place that can discern UFOs while they're still cloaked,' and that if the 'non-human' craft land, crash or are brought down to earth, special military units are sent to try to salvage the wreckage. Sources said the CIA office then often hands the wreckage or material over to private aerospace contractors for analysis, where it is not subject to rigorous government audits and can be shielded with protections for trade secrets. Multiple sources said that many of the people involved in these programs may not even realize they are dealing with non-human craft.
