Shape of the ufo flash is flat that is different from those of airplanes and stars. no satellite flash can be seen with this camera (sony hdr cx-390 with unmagnification mode) at this mid-night - 10:25 p.M.). you can hear the sound of ocean waves unfortunately the uploaded footage is compressed and deteriorated, which makes it very difficult to recognize the first flash of light. if two flashes are of the same one object, its speed must have been far outstripped any airplane on our planet. actually flat shape of flash is very rare, both the lights would have been flashed by the same flying object that is most likely ufo. the latter part of this video shows airplane flash.. the last part shows similarities and differences between ufos (flash) i recorded and airplanes & stars. in the case of airplane light, large flash has brighter and clearer figure than those of smaller flash, however, the flash i recorded this time has clear flat figure in spite of its smaller size, which is the point that i felt something is strange from my experiences of seeing hundreds of airplane lights in the sky. then i realized that this flat flash is similar to the blue flash i videotaped at night in tokyo in 2015. i also attached its video here.
