The US has been accused of hiding evidence of UFOs from the public during a bipartisan congressional hearing on Thursday (May 1). A number of experts spoke to government officials ... at the briefing on unidentified anomalous phenomena (UAP) - as it is becoming more commonly referred to these days - about the possibility of alien life. The House Committee on Oversight and Accountability ... held the event called 'Understanding UAP: Science, National Security & Innovation.' Scientists told the members of Congress that they required a bigger part in the role of investigating UAPs and other unexplained phenomena. Key speakers included former Pentagon official turned UAP whistleblower Luis Elizondo and Harvard astrophysicist Avi Loeb. Research physicist Dr Eric Davis said the US government has been operating a secret program recovering crashed UFOs since the 1950s when Dwight Eisenhower was president. Dr Davis worked as a subcontractor and then a consultant for the Pentagon UFO program since 2007. He claimed that the program began after the discovery of a crashed UAP in 1944. Since then he said that a lot of the technology recovered over the years from these wreckages have been secretly moved to Wright Patterson Air Force Base in Ohio, without any congressional oversight or approval. He once concluded that we couldn't make it ourselves" after seeing some of of the recovered materials himself.
