These kinds of UFOs are in triangular shape with rounded shape on their corners. They are usually seen as black with a whining sound. They fly on an amazing speed horizontally and can be seen somewhere.
In 1965, the appearance of this triangle UFO was witnessed and recorded, but no distinct place of sighting to substantiate. People speculated that the flying object was one of the military projects which are the new generation stealth aircrafts. This craft sighted flies the same way as on 60's until now which brought UFO and Extraterrestrial enthusiast to wonder why aircrafts on 60's fly the same way till today.
According to them, that triangular UFO or the new generation stealth aircrafts use engineering techniques that were passed from extraterrestrials to human civilization globally.
Believers alleged the fact that the triangular UFO uses superconductors that produces electromagnetic flux and anti-gravity propulsion that makes a whining sound. In fact, this kind of crafts is already present in some countries worldwide and they strongly believed that it is due to the transmission of engineering techniques by extraterrestrials to human civilizations.
While some groups of people strongly believe on it, others also find the theory silly or stupid. Still, believers persist that the theory is true in accordance to people who had sighted from different places with the same testimony. In additional, the principles used on these UFOs meet the standards present on aircrafts we have today. Again, they say it is because of alien civilizations that have been assisting humans over the years.
UFO researchers believe that there is high possibility that they exist and they are just disguising somewhere over the world. However, ministries and departments of defense from different countries involved stayed mute while some are denying the issue. They do not entertain such claims of triangular UFO sighting and suspicion of human-extraterrestrial collaboration.
However, claims of this triangular UFOs have never been proven by evidences to prove their existence. According to some scientists that these claims of such UFOs are just illusions and they are just sighted one of the aircrafts souring the sky.
