Corrected entry: To enter the central sector of the alien spaceship, David, the android, cleverly types some signal that causes the door to open. We see him climb a silver metallic ladder to reach the necessary keys to make this happen. Where did this ladder come from? The crew did not bring it, and it was not shown prior to David using it.

Correction: It was a telescopic ladder, and it was in one of the supply packs that the crew were carrying.
