Description: On 3/21/12 at 8:45 PM it was a clear night. I was watching a jet liner heading NE at 30,000 feet minimum. I was in between two houses when I saw an orange ball of light moving at incredible speed. it flashed on and off 5 times over 4 seconds and covererd 20 miles. It traveled north to south at 7,000 feet. There was no sound. There was no flame or contrail. This was not a meteorite. It was in our atmosphere. It was maybe 100 feet across and like an orb. I have never seen anything like it and probably never will again.Note to Commenters: If you are reporting a sighting, be sure to include the location (city, state, country), date and time of your sighting.
