Shortly before the crash, several witnesses described seeing an aircraft flying unusually low towards the Continental Divide. Some witnesses located on higher mountainside locations, such as Loveland Pass at , reported seeing it flying below them. Crash survivor Rick Stephens was a senior guard and stated in 2013, "...as we flew along over I-70, that there were old mines and old vehicles above us. I noticed we were quite a bit below the top of the mountains. I got up to go to the cockpit, which wasn't unusual to do, and I could tell we were in trouble, looking out the window and seeing nothing but green in front of us."
