A brother and sister alien hunting team have discovered a “UFO highway” across America along which hundreds of unexplained events have taken place - from cattle mutilations to alien abductions.

Chuck Zukowski and Debbie Ziegelmeyer have spent years travelling across the US investigating hundreds of UFO sightings and other paranormal occurrences.

It was during one cattle mutilation investigation that Chuck realised that many of the unexplained events he had looked into had taken place on the 37th latitude.

He called his sister - who noticed the same with her investigations in Missouri - and the pair began researching the phenomenon, discovering that there are clusters of unexplained events taking place across the same latitude line.

The pair believe that the 37th latitude line is a kind of UFO or paranormal “highway” along which extra terrestrial craft enter and exit the earth.

Their theory is now the subject of a book called the 37th Parallel - and is about to be made into a Hollywood blockbuster in the next few months.
