It was dark out already and there was a fair degree of light pollution from stores, ect. Suddenly I saw what I thought at first was a bright white light of a plane or more like a jet streaking down rapidly towards the earth, across the main drag I was traveling on. It gave me momentary panic because a plane had crashed just beyond the intersection ahead maybe 8 yrs back and this bright light was traveling roughly in the direction of the nearby airport. However, I quickly intuited that it was moving much too fast for a plane, and jets don't land at that airport. Also my mind realized I wouldn't be seeing the bright thickening streak behind a jet at night, especially coming in that fast and bright near a city ( thus I was thinking something was crashing). And the light increased as it streaked toward the ground, and my eyes were following it cause I thought if it were a plane about to crash then 1) it would be blinking in some manner (we see tons of planes) 2) I was expecting the light to continue to get brighter and then maybe a fiery wreck/ explosion/ flames somewhere... and the white did seem to grow larger and then have harvest gold surrounding the front leading ball part of it, but just before it should have disappeared behind the buildings of the horizon, it just totally blinked out and disappeared. That was part of the weird thing, my view of it didn't get obscured by anything on the horizon, it just was growing brighter as I would expect something on fire nearing the earth to do, and then just went black and disappeared before the trajectory it was impeded by some object that would have blocked it from my sight. That, it's speed and brightness so out of place within a commute I've done a thousand time, and it's odd disappearance (which as a person who draws landscapes and is aware of how perspective, etc work, knew that if it was a plane or unlikely jet or something going down (not over where the airport was but sooner), then that thicker line of light would have grown even larger and went farther down in my field of vision.
