Continuity mistake: Adrian and Le Borg are flying on a modern-day commercial jet. Just after the explosion, there's a quick aerial shot of the plane plunging from the sky. However, the airplane in the scene is definitely not a jet, as seen by the shape of the wings. This appears to be stock WWII film footage of a military fighter plane that was shot down.
Continuity mistake: At the beginning of the movie the spaceship has three runabouts affixed to the bottom of the hull. The middle one is used to travel to an unknown spaceship and is blown up. Immediate subsequent shots of the outside of the spaceship show the middle runabout missing. But after a while, outside shots show all three again nestled in their bays.
