Xylert Aircraft

An open portal at the coordinates of 69 degrees south of 187 degrees west longitude. At this point suddenly there is a black hole that can connect between galaxies. When the portal opens, flashes of the spectrum of colorful light. An alien plane with the Xylert code goes into the Earth's atmosphere and chooses a place far from humans. The shape is like a UFO plane i fiction film. It is about 30 meters in radius. The height is about 7 meter. The place they are headed is the south pole. A region far from settlement and not inhabited by humans. When this plane arrived it turned out that there were already several squadron planes there. When the xylert plane is about to land they emit waves that are returned by other aircraft. They have sent signals aimed at humanity. however, it turns out that experts in developed countries still have not managed to translate these signals. Too high a frequency with waves above ultra sonic waves. Meanwhile, they also circulate super electromagnetic waves. This wave has a spectrum that is higher than gamma rays. From a human perspective, it can only capture the phenomenon of aurora at the poles. Even though it is a type of communication signal that emits from alien planes. When these auroral rays collided with each other it showed communication. At that time a student was conducting an experiment to make a transmitter that could capture foreign waves. He knew that this was not an ordinary wave. Ma, he keeps trying to fix it. after adding IIC which can receive ultra high frequency waves suddenly it receives a regular wave beam. he felt this must be someone trying to contact. he then returned the wave with a tap of a morse password. This knock was able to give the wave that was returned again. Knocking after the beat is done rhythmically while continuing to fix the tool. each beat will be returned. frequency and number of beats are answered differently. over time he tried to beat anyway. the answer also remains the same. During the day he made communication that he never understood the meaning. Finally he decided to contact NASA to inform him of the wave he had caught. NASA's positive response provided hope for further communication with the waves which turned out to be from Xylert aircraft. Thank you @xpilar. I hope you accept my thought. Warm regard from Indonesia
