There is no evidence yet to say aerial phenomena seen by the pilots of the United States Navy were alien spacecraft, the New York Times has said citing senior administration officials. However, US intelligence officials also do not have any explanation for the mysterious unusual movements witnessed by the pilots, the report added.

The NYT has reported the findings of a yet-to-be-published US government report on unidentified flying objects or UFOs. The US military now refers to these craft as UAPs or unidentified aerial phenomena.

US officials, who were in the know of the government report findings, however, confirmed that the sightings were not of any American military aircraft or other advanced US defence technology.

The government report confirms that there is no evidence to link a majority of the over 120 incidents reported over the past 20 years with secret Pentagon technology.

What has mystified US scientists and military regarding the sightings is these craft’s unexplained ability to unusually accelerate, change directions and rapidly submerge.

One senior official, who was aware of the report, said there was a concern among intelligence and military officials that the phenomena could in fact be hypersonic technology experiments being conducted by China or Russia.

The report is likely to be released to the US Congress by June 25 and will have both a classified version and an unclassified version, which will eventually be available in the public domain. The classified annexe of the report is expected to trigger speculation that the aerial phenomena did in fact have something to do with aliens.

NYT reported senior officials as saying that the ambiguous findings mean the government has little to definitively rule out the link between aerial phenomena and alien spacecraft.

Last year, several videos were released by the Pentagon showing US Navy pilots’ mid-air encounters with unusual aircraft.

Last month, former US president Barack Obama went on record to say they did not know what actually those crafts were.

“What is true — and I’m actually being serious here — is that there’s footage and records of objects in the skies that we don’t know exactly what they are,” Obama said on the “The Late Late Show with James Corden” on CBS.
