SHEFFIELD -- Matt and Thomas Reed were sitting in their family home on Boardman Street one evening in September 1966 when their first experience with extraterrestrial life occurred, they say.

Thomas, who was 6 at the time, recalled flashes of light emitting from the Frisbee-shaped object that landed in their yard. It felt like the pressure in the house changed before the brothers inexplicably found themselves on the other end of their property, face-to-face with beings not of this planet.

"I don't run with terminology, but what they looked like was a young, frail human with some characteristics that some might reference as odd-looking beings," Thomas said.

"They put off some type of glow," he said. "I was able to see my brother clearly enough."

And the Reeds have the evidence to back up their claims, much of which will be presented on March 3 during the premiere of "Alien Mysteries," a new show on the Discovery Channel in Canada. The episode will eventually be aired in the United States.

The Reed family's story is the subject of the new series' pilot episode.

"The reason we put it first is because they're just regular people who have had amazing experiences," said Sally Karam, the show's producer. "I think their story is, for many reasons, very strong."
