A shocking incident occurred in the U.S. state of Alaska, where an unidentified flying object was captured on video from the cabin of a large cruise ship in the middle of the night.

The footage shows a mysterious, bluish-white capsule-shaped object flying from the ocean surface into the sky. Records indicate that this event took place at 1:18 AM on May 30, 2019.

That night, thousands of passengers aboard the cruise ship were enjoying the beautiful Alaskan night in their own way. However, only the automated observation and recording robot, SID-1, noticed something happening at midnight. SID-1 immediately captured and recorded the mysterious sight.

The video captures a highly otherworldly scene in which a bright, bluish-white capsule-shaped object ascends rapidly from the sea surface, as seen from a cruise ship cabin floating on the quiet midnight ocean.

The object had a distinct shape and illuminated the surrounding darkness. It was unlike common aircraft such as airplanes, helicopters, or drones, making it an extraordinarily unusual sight.

Later image analysis led researchers to hypothesize that it could be a reflection from ship lights, a natural phenomenon, or ground lights. However, the bluish-white light emitted by the capsule shape differed from any known natural occurrence. As the analysis progressed, it suggested the possibility that this was a UAP (Unidentified Aerial Phenomenon). The capsule shape and movement did not resemble conventional aircraft or known flying objects, hinting at an unknown technology with unique flight capabilities.

Given that there have been past UFO sightings off the coast of Alaska, this event gained even more attention. Alaska is known for frequent UFO sightings, with many reports over the years. However, no past recorded footage has provided such clear evidence as this video.

Experts and researchers attempted to unravel the mystery of this object based on the footage, but no definitive conclusions have been reached. This incident has drawn worldwide interest from UFO researchers and aviation experts.

The UAP video can be viewed here:

In this case, the position of SID-1, its altitude above the sea surface, and the depression angle from the lens to the UAP are clearly recorded by SID-1. Based on this data, the distance to the UAP, as well as its size and speed, can be determined.

As shown in the diagram, a right triangle is formed by the depression angle θ from the lens to the UAP and the altitude h1 above the sea surface. From these values, the base L1 and the hypotenuse L2 can be calculated. The hypotenuse represents the direct distance from the lens to the UAP. By analyzing the field of view in the image, the UAP’s shape, size, and ascent speed can also be determined.

Using SID-1’s images and referencing the ship’s length, the height h1 from the ship deck to the cabin was calculated. This revealed that the height from the water surface to the SID-1 lens was 39.7m.

From the field of view, the depression angle from the lens to the UAP was calculated to be 5.63 degrees. Using this, the horizontal distance L1 was determined to be 402.7m, and the direct distance from the lens to the UAP, L2, was 404.7m. Similarly, calculating the UAP’s dimensions resulted in a capsule shape with a diameter of 2.6m and a length of 4.6m.

The UAP’s length was calculated as:
UAP Length = L1 × tanθ = 402.7m × tan(B) = 402.7m × tan(0.66°) = 4.6m
UAP Diameter = 2.6m

Calculating the speed of the UAP after emerging from the ocean, it was found to be 297 m/s (1,069 km/h), indicating an extremely high velocity.

The ratio of the long axis to the short axis is 1.80:1.00, a familiar figure. Not only does its shape closely resemble a UAP officially recognized by the U.S. Department of Defense (DoD), but the long-to-short axis ratio is exactly the same at 1.80:1.00. It became evident that a UAP of the same shape was recorded by SID-1 in Alaska.

While this incident involved a UAP emerging from the sea, there is also leaked footage showing a UAP—approximately 2 meters in diameter—vanishing into the sea or seemingly disappearing above it.

In July 2019, a swarm of unidentified objects surrounded multiple U.S. Navy warships off the coast of San Diego. The USS Omaha encountered as many as 14 UFOs simultaneously and monitored the UAPs encircling the vessel for nearly two hours on the night of July 15, 2019.

One of these UAPs emitted its own light and registered a temperature higher than the surrounding seawater. It flew in parallel with the Omaha for an extended period before seemingly vanishing into or beneath the ocean.

Furthermore, this similarly shaped UAP has been recorded multiple times by SID-1, not only overseas but also in Japan.
