Falling star like light object making erratic maneuversOn Saturday, January 10th 2009 at approximately 6:10pm in the early dark evening, I witnessed the following account. About a mile north before the city of Bountiful, Utah traveling south on I-15, I saw above me through the front windshield a bright white/yellow falling star traveling north to south my same direction. The “star” traveled quickly across the sky then “stopped in mid-air” over what appeared to be the ensign peak area between Bountiful and SLC. This startled me and I said, “What the heck is that?”. No falling star here as the light then moved back north east over North Salt Lake and made a slow wide circling pattern as if it were going to land. At this point my wife said, “Maybe it’s a helicopter going to land”. The light then traveled west quickly across the interstate and suddenly maneuvered straight up for about 300-500 feet over I-215 just south of the Legacy interchange. After that it traveled south towards the 7th north exit in west SLC desending at a high rate and disappeared from our site. I am a private pilot and aware of natural speeds and maneuvers a “normal” plane or helicopter would make, but this to me seemed to fast and erratic in behavior. My wife thought she could see blinking lights around the main light. I could not see position lights only the white/yellow light it emitted from all angles. Besides, this is controlled airspace, would Salt Lake Center allow this kind of evasive maneuvering? I was curious to hear if anyone else saw what we witnessed so I called an FAA flight briefer and he gave me the number to this reporting site.
