A ‘genius’ who said he had been in touch with aliens vanished off the face of the Earth more than four decades ago.

On a stormy night of November 29, 1980, Granger Taylor disappeared from the Canadian town of Duncan, with the mystery of what actually happened to the 32-year-old still ongoing to this day.

Taylor reportedly left a note to his family, claiming he was preparing for a voyage aboard an alien spaceship - but promised he would return.

The prodigy also alleged he could communicate with aliens, and to this end had built a life-size replica of a spacecraft from parts he accumulated from the local dump.

His sister admitted to Vice that Taylor was known to take acid a ‘few times a day’ in the lead up to his disappearance and was known for dabbling in smoking cannabis.

And then he vanished out of thin air, leaving behind a note and all his Earthly possessions to his family.

In the note, Taylor said he was jetting off on a lengthy interstellar trip for three and a half years, but apparently never made it back home from wherever he had gone.
