The following links will take you to examples of Billy Meier's remarkable and still irreproducible physical evidence. While some people have managed to create similar visual effects, to date no one who claims to have duplicated Meier's photographic evidence has ever had their UFO photos tested to the same standards as the ones that established the authenticity of Meier's. The reason is quite simple, such testing will reveal the undisputed facts, i.e., that all such efforts were done with small models close to the camera, while expert analysis revealed that the UFOs in Meier's evidence were large objects that were farther away from the camera.
And here you will find an actual sound recording of a Plejaren UFO, which was also found to be irreproducible even with synthesizers when tested and analyszed.
