Senior members of Congress have spoken to as many as six whistleblowers who claim they worked on Roswell-style UFO crash retrieval and reverse engineering programs. Congress passed a law last year creating whistleblower protections for anyone who has worked in such mind-boggling secret programs. Daniel Sheehan said he is in contact with at least six former government officials or military contractors who say they worked on just such a program. Sheehan says witnesses who allegedly know about Roswell-style programs, including a former Defense Intelligence Agency director, have been referred for interviews with the Pentagon's UFO office, the All-domain Anomaly Resolution Office (AARO). Immunologist and Nobel Prize nominee Dr. Garry Nolan was commissioned by the CIA to investigate cases of the mysterious Havana Syndrome inflicting embassy officials worldwide, and has conducted experiments analyzing material allegedly jettisoned in UFO flyovers. He claims to be in contact with several former staffers of extraordinary UFO 'reverse engineering' programs. Another Nobel Prize nominee and CIA scientist Dr. Hal Puthoff, who worked in the government's 2008-2012 UFO program called AAWSAP, told DailyMail.com that he had briefed congress on classified information about reverse engineering programs, and knew of whistleblowers who had worked in the alleged programs. AARO has 72 hours to report to Congress any program discovered that has not been properly reported.
