Visible crew/equipment: In one of the scenes where Nia Peeples is fighting with Ja Rule and Steven Seagal, she jumps down to a lower level corridor, and you can see the pad that she or the stunt woman lands on.
Factual error: A two minute free fall from a helicopter? Not unless the helicopter was flying at 230,000 feet, which is more than 5 times the record altitude achieved by one.
