This was seen on a very clear and low humidity night. The fireball appeared out of nowhere from almost directly overhead and appeared to travel directly down into the south-south east horizon. It had a steady and bright amber white "flame" with a very little to no trail. It seemed to fall at a relatively slow rate of speed similar to what an aircraft would travel at after loosing it's power and gliding/crashing down to earth. It did not streak across the sky like a high altitude meteor might do during a meteor shower. It was bright and eerily silent. It seemed to be not more than several miles high overall.
I and a neighbor both watched it outside from the street level when facing south. It's duration was about six to seven full seconds before being blocked from view by a nearby two story apartment building directly 100' to the south of us. It was about 22 degrees over the horizon when we lost our view of it. It is the longest lasting and brightest fireball I have seen in my lifetime of 55 years. To myself it seems that it may also be from a manmade object breaking up after falling out of orbit or from high altitude flight because of the way it seemed to glide down and also "burn" with a consistent light yellow brightness and similar to a candle's flame with some minimal flicker which I found unique and unusual.
