It would be impossible to have enough fuel to fly into the Sun...
further, when the passengers of the shuttle disembarked on the moon-well, THAT was highly inaccurate-THERE IS NO AIR ON THE MOON! They all would have died! if the schools would only teach science these days!
Saw a gal on the moonbase-wearing a NOSTROMO cap-TOTALLY impossible since ALIEN took place much further into the future...this film WAS SO FULL OF INACCURACIES! Im writing to Paramount!!!!!!
