green fireball streaking across the ski in a southwesterly direction

I was doing a winter contract at McMurdo Station in Antarctica. My partner and our helper and I were out on the ice shelf at the runway readjusting the runway lights. I was down in a hole digging out a transformer when my partner exclaimed "did you see that!" Our helper said yes he did. I asked what happened and they told me a bright green light went streaking across the sky. It was still daylight at the time and clear sky since the sun hadn't set then. We figured that it was a meteor and had copper in it to give it the green color as it burned through the atmosphere. I was listening to you on Art Bell on the Sept 25 show and you mentioned no sonic boom. That brought to my mind about the above sighting... there was no sonic boom. We were basically out in the middle of nowhere... McMurdo being six miles away so the only noise being made was by us. Not sure now if what they saw was a meteor or not. It was seem by other people in the town too from what we heard when we got back. My partner and I are both electricians and our helper was just learning. Not sure what else you may need. My email is ((deleted)) if you need more and phone is 314-((# deleted)). I report this now since the green fireballs you were talking about to Art brought the memory back to me.
