Washington: US intelligence officials have found no evidence that aerial phenomena witnessed by Navy pilots in recent years are alien spacecraft, but they still cannot explain the unusual movements that have mystified scientists and the military, according to senior administration officials briefed on the findings of a highly anticipated government report, reports New York Times.
The report determines that most of over 120 incidents over the past two decades did not originate from any American military or other advanced U.S. government technology, the officials said. But that is about the only conclusive finding in the classified intelligence report, the officials said. And while a forthcoming unclassified version, expected to be released to Congress by June 25, will present few other firm conclusions.
Americans’ long-running fascination with U.F.O.s has intensified in recent weeks in anticipation of the release of the government report.
The report concedes that much about the observed phenomena remains difficult to explain, including their acceleration, as well as ability to change direction and submerge. One possible explanation — that the phenomena could be weather balloons or other research balloons — does not hold up in all cases, the officials said, because of changes in wind speed at the times of some of the interactions.
The final report will also include a classified annex, the officials said. While the annex will not contain any evidence concluding that the phenomena are alien spacecraft, the officials acknowledged that the fact that it would remain off limits to the public was likely to continue to fuel speculation that the government had secret data about alien visitations to Earth.
Many of the more than 120 incidents examined in the report are from Navy personnel, officials said. The report also examined incidents involving foreign militaries over the last two decades. Intelligence officials believe at least some of the aerial phenomena could have been experimental technology from a rival power, most likely Russia or China.
One senior official briefed on the intelligence said there was worry among intelligence and military officials that China or Russia could be experimenting with hypersonic technology. Russia has been investing heavily in hypersonics, believing the technology offers it the ability to evade American missile-defense technology. China has also developed hypersonic weaponry, and included it in military parades. If the phenomena were Chinese or Russian aircraft, officials said, that would suggest the two powers’ hypersonic research had far outpaced American military development.
Navy pilots were often unsettled by the sightings. In one encounter, strange objects — one of them like a spinning top moving against the wind — appeared almost daily from the summer of 2014 to March 2015, high in the skies over the East Coast. Navy pilots reported to their superiors that the objects had no visible engine or infrared exhaust plumes, but that they could reach 30,000 feet and hypersonic speeds.
The Defense Department has been collecting such reports for more than 13 years as part of a shadowy, little-known Advanced Aerospace Threat Identification Program within the Pentagon. The program analyzed radar data, video footage and accounts provided by the Navy pilots and senior officers.
The program began in 2007 and was largely funded at the request of Harry Reid, the Nevada Democrat who was the Senate majority leader at the time. It was officially shut down in 2012, when the money dried up, according to the Pentagon.
