I live near Mcghee Tyson airport in Alcoa Tennessee on the fourth floor of a highrise condominium complex that faces the North West.I can see planes circling and preparing to land all the time at night. I was not watching out my window until the bright light caught my attention through a window.It really just appeared and was instantly bright.I had never seen a plane that bright or moving that fast that would be coming in for a landing,and then it just disappeared.I observed it for around 30 to 45 seconds at a guess.
