Description of Area / Surroundings

Spotted over interstate 55 going through part of the city of Joliet near the exit for Rt. 30. There is a municipal airport for the city of Joliet however neither my girlfriend nor I recall seeing any other aircraft that were obviously helicopters or airplanes.

Full Description & Details

Around 21:15 on the 21st of April, 2012 my girlfriend and I were driving south on interstate 55 near the city of Joliet Illinois. SHe was driving and noticed three peculiar lights in the sky that individually resembled small balls of fire. They were gliding in a triangle shape at a constant speed. Our car was going at around 70 mph. At first I thought they may have been low flying helicopters or remote control airplanes.

I have spent some time in the U.S. Air Force and am familiar with many different kinds of aircraft but after watching the lights for a little bit decided that I have never seen lights like those on any kind of aircraft previously.

We noticed that off to the east there was one more solitary "fireball" flying low over the horizon. It appeared to be moving at the same rate as the three lights above us. It was partly cloudy that evening so judging the height at which the objects appeared is difficult but I would approximate it at a thousand feet or so.

I opened my passenger window to see if I could hear any type of engine noise but heard nothing. Granted, I was in a moving car on the highway. The lights eventually passed overhead heading north. The light at the tip of the triangle eventually faded out but the two at the base just kept flickering off into the distance until they were out of sight.

Background info on observers:

Can sighting be explained as any conventional man-made or natural object?

I served in the U.S. Air Force from 1997-2001 and have seen many different types of aircraft including helicopters, jets, gliders and bombers and do not believe that the object my girlfriend and I saw that night could have been any of these. We are also very interested in watching and naming the stars & constellations in the sky and very often use the googlesky application to determine what we are looking at. The lights we saw that evening were not Venus, Jupiter, Sirius or any other celestial body. It was simply too low and moving at too constant of a rate to have been a star, planet, meteorite etc.
