LV-426 after all.....

from watching the most awesome trailer...after many times...looking we see the iconic space jockey crash coming down from the sky in a ball of fire as some of the crew members, perhaps the ones remaining alive are responsible for the crash of the space jockey and...yes, being on LV426 after all...could the beacon have been planted by the remaining survivors of the Prometheus expedition? So much friends...so much to think about and discuss!
