Passengers of the plane, following a flight from Japan to the island of Taiwan on May 1, 2017, filmed a bright UFO with a wide light yellow trail flying over the Pacific Ocean through the window glass (see video below).
A fiery object with indistinct outlines, which most likely has an energy structure, was moving at great speed on the right side of the passenger airliner, leaving behind a translucent trail with a stunningly beautiful pattern.
The contours of the trail constantly changed during the movement of the object, then for a few seconds the luminous core in front took the shape of an oblique infinity sign and disappeared, as if it had "dived" into the long tail, and immediately the bright glow shifted to its rear.
Then the luminous UFO reappeared in front of the sky locomotive racing at full steam. Apparently, at this moment, the UFO changed its direction of movement and began to quickly move away from the aircraft, while its tail became either longer or shorter, as if it was thus correcting its course.
