Chuck Zukowski and Debbie Ziegelmeyer have spent years travelling across the US investigating hundreds of UFO sightings and other paranormal occurrences.
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.
Chuck told Sun Online: “Back in 2006 I was looking at my cattle mutilation investigations - there were huge similarities between them all - most of them were laying on their right side, they’re laying east to west and then I noticed that lots of them were on the 37 degree latitude.
“I called my sister at midnight and I said, ‘Didn’t you have cattle mutilations on the 37 degree latitude in Missouri?
' "And she said, ' Yes' and we started looking more into it.
A local Air Force base claimed the debris came from a crashed hot air balloon, but many people reckon it's really the remains of a flying saucer.The number of UFO sightings is currently flying at an all-time high, according to data cruncher and blogger Sam Monfort.The alien expert reckons there have been more than 100,000 recorded UFO sightings in the past 100-plus years.There's even a clip of a UFO supposedly attacking a Taliban compound, as well as 'sightings' in Peckham and Warminster. In the M5 clip, for example, the motorway lorries look like models.While the Peckham UFOs were "almost certainly Chinese lanterns", former Ministry of Defence UFO investigator Nick Pope told the Sun Online.
