Environment Canada and the Transportation Safety Board of Canada can't explain just what it was a P.E.I. couple filmed in the Island skies on Wednesday evening.

When Tony Quigley and his wife Marie of North Tryon, just east of the Confederation Bridge, saw a dark spiral in the sky they went for the video camera.

"When we first saw it, it was going so slow. We said, is it a meteorite, or what the heck is it? So when we did start to tape, it was above the cloud and that's the part we missed," said Marie Quigley.

"When it came out of the cloud, we have it from there until it's out of sight. I have no idea. I mean I didn't think it was a UFO or anything but to me I thought something was in trouble, but it was going so slow. I mean it was at least a half an hour from the time we first spotted it till it went out of sight."

The couple has no clue what it was. Their first calls, to the Charlottetown Airport and the RCMP, were no help. They called Environment Canada, which was also unable to identify the phenomenon.

The Transportation Safety Board of Canada has reviewed the footage to ensure the sighting was not of an aircraft in distress. A representative from the board confirmed it was not, but had no further details.
