Bright green light ball flying circular, oval in shape flew over my house tonight and above trees.Bright, green, light also white in color possible fireball flew over house and across street about 20ft above trees approximately 10:02pm. It was completely dark outside. Disappeared out of sight once on other side of tree sight. Not enormous in size, but rather large. Hard to determine size really. It was a ball. Kinda oval and circular. There was no sound at all. No jet trails or streams. Lasted about 4 seconds. It glided smooth and went across and over the trees. About 5-10 minutes later there were numerous jets with lights on both wings flying low going towards direction. Also numberous helicopters.((NUFORC Note: We spoke via telephone with the witness, and she stated that the apparent size of the object was larger than that of a full Moon, and perhaps several times larger. Her impression was that it was not a meteor, contrary to local news reports. PD))
