Falling object becomes stationaryOn February 18, 2009, I was flying from Houston Texas to Jacksonville Florida, I was sitting on the left side of the aircraft (commercial airliner, not sure of the altitude) at a window seat. It could have been about half way through the flight when I noticed a trail of smoke coming straight down toward the ground (vertically) as I watched it the first thing that came to mind was a satellite because I had just read about an American and Russian satellite colliding in space. As I watched it it changed to a horizontal direction and then remained horizontally. I watched it with out taking my eyes of it, it reamined in this position and what appeared to be stationary until the aircraft passed it. It seemed pretty far away as the aircraft became parallel to the object.((NUFORC Note: Witness elects to provide no contact information. PD))
