When you see the DeLorean landing or taking off... it's a small 18" model built by George Lucas's Industrial Light and Magic... A wonderful toy, built to the tune of $130,000. The only problem with their attention to detail is the missing keyholes in the gullwing doors. (small black circle, just above and behind the door handles) When the DeLorean begins to land in Hilldale, there's no keyhole, yet, seconds later, when the full size DeLorean is being lowered with an off screen forklift, you can clearly see the keyhole, as every real DeLorean has. Simply a small detail that was missed. That and the fact that real stainless steel reflects light, whereas a tiny plastic model with silver paint, does not.. also clearly seen in this scene as well. No match.
