An Illinois witness posted a video presentation about a May 8, 2010, triangle or boomerang-shaped UFO sighting that occurred on a flight to Chicago, according to testimony from the Mutual UFO Network (MUFON) witness reporting database.

The witness believes the flight was near the Illinois border as it flew into Chicago at the time and was near a nuclear power plant.

Illinois, May 8, 2010 - UFO flying near nuclear reactor 08 May 2010. MUFON Case # 23242.

I caught this triangle, boomerang, crescent-shaped UFO while flying home to Chicago from Dallas/Fort Worth on 5/8/2010.

At around 6:23pm CDT I noticed a grey silhouette of what at first looked like a cigar hanging in the sky. I immediately took my camera out from my carry on and first took photos, then recorded video.

I have seen this craft numerous times now. I am pretty sure it is the same craft that was hit by lightning in my other video Easter Sunday.

After the UFO flew away the airplane I was in flew over a nuclear reactor. I had no idea where I was exactly. I believe near the Illinois border flying North toward Chicago.
