Location: Lincolnshire, IL
Shape: Triangle
Duration:3 seconds
Triangular symmetric object flying low in a straight line over North Shore Chicago suburbs.

After parking in the driveway of a Private residence near Riverwoods Road, I noticed what appeared to be a small brown-beige triangular shaped object traveling approximately parallel to Riverwoods Road (from south to north). It appeared nearly overhead, was silent and its speed I would estimate to be approximately 50-60 MPH.

The object had symmetry forming an approximate 25 degree angle from its apex toward the aft part of the object. The object had bilateral surface detail suggesting nacelles in a fuselage. They were very definitive. The object did not appear to be very large, being about the size of a larger radio controlled aircraft.

It flew in a straight line and constant speed for the brief time I had it in view.

I lost it as it passed over the treeline to the north, this being a heavily wooded suburb of Chicago. I would estimate the altitude at less than 500 feet AGL.
