CLEVELAND -- Experts say the Cleveland area is a hotbed for UFOs.

For many, the idea is a joke. But others are not so sure. However, one local group has absolutely no doubt -- in their view, we are not alone.

NewsChannel5 began with the premise that UFOs are out there. After all, if people see something in the sky and don't know what it is, then by definition it remains "unidentified," at least until it is identified.

Aaron Clark is one of many UFO investigators and a member of the Cleveland Ufology Project.

The group is not new. It's been around since 1952.

NewsChannel5 reported that Cleveland has the most UFO investigators in the world.

Some experts speculate on why northeast Ohio?

"There are unusual things that are manmade here. Quite often they appear to show curiosity with new construction building a dam or a factory or something, and there is a UFO sighting in conjunction with it," said UFO investigator Richard Lee.

Two years ago, Olmsted Falls police officers followed bright lights in the sky after receiving numerous phone calls from residents who saw strange green and red lights moving across the sky. They were never identified.

Since then there have been at least 20 reported sightings in northeast Ohio.

Thousands of sightings are reported every year worldwide. But experts say just as many go unreported because of skepticism.

They say for people who see something in the sky, it's a life-changing experience.

"Affects their life, affects their religion, affects their relationships. I've known people who have become divorced because of their experiences," said Lee.
