Factual error: In the scenes where Daniels and Salt are flying together in the helicopter, the pilot, Salt, would be in the right seat. Although it is possible to fly the helicopter from either seat, the primary controls are on the right of the helicopter (Loach, Hughes OH-6 included). Even an inexperienced pilot would never jump into the left seat when the other person has no flight experience. Left seat primary controls are in fixed wing aircraft.
Factual error: When the camera is panning through the different rooms of USAMRIID it exits out of BSL-3 and as it does a female technician takes her breathing mask off before she opens the door. This is supposed to be the highly infectious room that tests things like Anthrax or H.I.V. yet this woman not only takes her mask off she's not even quarantined or decontaminated.jbrbbt
Factual error: At the beginning of the movie, a military plane that appears to be a DC-3 drops a large bomb out from its tail area. Problem being, the DC-3 has no door under its tail, as is found on modern military transport planes or the one used at the end of the film. The DC-3 only has side doors.
Factual error: When Sam Daniels and Casey are walking to the BSL-4 lab we see the shoulder insignia on Casey's coat are silver oak leaves. Silver oak leaves are the insignia of an O-5, Lieutenant Colonel, but Casey is supposed to be an O-4, Major (which would be represented by gold oak leaves). The only possible explanation is that Casey was promoted after the trip to Zaire, however this is extremely unlikely; if he were promoted to O-5 he would likely be given his own crew and no longer a member of Daniel's staff.
