When Will Smith and David were on their way to the big alien ship to deliver the computer virus, the spaceship makes its weird little turining noise. (rrrrrerrr) After this, there is a close up of the ship the humans are flying in. As the spaceship (the one with the humans in it) flies away from the close up, there is an audible "whoosh!!!" These noises are not possible as there is NO sound in space. Actualy, every sci-fi movie containing spaceships EXCEPT for 2001 a space odessy has a "whoosh" sound when the spaceship(s) pass the camera.
