Sailors have reported a mysterious sighting as they crossed the Atlantic this month.

A submission to the National UFO Reporting Center (NUFORC), dated October 11, detailed an encounter with glowing UFOs that the ship’s crew said moved at impossible speeds and patterns.

For about 40 minutes, two sailors watched through binoculars as a single orb appeared 12 to 16 miles away, which ‘rose and fell rapidly, bearing right and left, periodically shooting at hypersonic speeds, for about 5-10 minutes.’

The report, posted on October 21, claimed that three or four more orbs appeared, which looked the same as the first.

‘All twisting and turning, rising and falling together in no set pattern,’ the report states.

‘Every so often they went somewhere else altogether, at a speed I can only call unreasonable, and then were simply there again.

‘We picked up no targets on the radar.’

The NUFORC report included screenshots of the boat’s radar, reportedly taken during the encounter, showing nothing on the screens that would suggest objects were in the sky.

The witness said the encounter began around 3:25am, when the ship’s second mate spotted a strange light low above the horizon, slightly to the left of the vessel’s bow.

The ship was crossing the Atlantic roughly 400 miles south of Nova Scotia, heading east at about 20mph, according to the report.

The witness described clear skies with only a thin crescent moon, saying ‘visibility was great.’

The vessel was not noticeably rocking, and there was ‘no traffic whatsoever’ nearby.

After seeing the first orb, the sailor said: ‘The others appeared, 3-4 more. They were like the first in every respect.’

Another startling NUFORC report was submitted last year, featuring a video showing a clear image of what one witness believes was a giant UFO flying over California.

The April 27 video taken by an unnamed resident in Twentynine Palms followed what appears to be a brightly-lit hexagonal craft as it flew over the desert.
