Green ball of light falling from the sky(completely vertically down)Between the time of 11:55 of 10-3-2012 and 12:05 of 10-4-2012, a green ball of light was falling vertically. A friend was driving and i was riding passenger in the front. I had the window rolled down and looked to my right, when i saw this big green ball of light falling straight down. I didn't think it was a meteor or a comet, due to the light not having a tail or traveling semi-horizontally. It lasted about 5 to 10 seconds dropping behind trees and apartment complexes 2 to 3 stories high. It looked similar to roman candle flare but bigger and consistent and did not fade out, like a fire cracker would. It was much too high in the air to be from a fire cracker. Within 30 seconds after, a helicopter came flying from the south as we were pulling into my neighborhood. It circled my neighborhood about and passed my street, about 2 more streets down flying pretty low. Then i saw it go straight to the neighborhood where I saw the green ball of light fall. Then i! t left. I contacted the local news the next afternoon to inquire if anyone has reported anything. It's been 3 days and I haven't gotten a response.
