Again my argument is this...why would Bishop dangerously fly underneath the platform and not above it where he could clearly see Ripley? Also, despite the fact that Bishop "SAID" he was wired to protect humans, he knowingly allowed 2 face huggers to survive at the company's orders. Given the situation, he knew that the colonists had been wiped out by these creatures yet he chose to let them live. It seems to me his primary objective was to ensure the survival of the xenomorph by any means necessary. This was not too far off from the first android Ash. Funny how an android is standard procedure anytime the company sends people into an area full of aliens.
